How to enable hdmi digital audio on a laptop. No sound via HDMI when connecting laptop or PC to TV

The HDMI standard makes it easy to display image and sound from a laptop or computer to an external monitor or TV. To transmit picture and sound, just connect the computer to the device via a cable. But, as with any other data transfer standard, problems can arise with HDMI, including due to incorrect Windows settings. One of the common errors that users have to face is the lack of sound on the TV when connecting a computer to it via HDMI. There are several ways to fix this problem, which will be discussed below.

Please note: Before proceeding with the tips below, make sure that the lack of sound on the TV when connecting a computer to it via HDMI is not due to the settings of the TV itself. Often the reason is quite banal - the TV sound is reduced to zero or the “Silence Mode” (Mute) is turned on.

Selecting the correct playback device

When you connect an external information output device - a TV or monitor - to your computer via HDMI, the Windows operating system should automatically determine that the default sound will be broadcast through the connected source. If this does not happen for one reason or another, the user needs to independently assign the TV as the audio playback device. For this:

Important: If you don’t see a connected monitor or TV in the list of available playback devices, right-click in any empty space and check the “Show disconnected devices” and “Show disconnected devices” checkboxes. Try to find a connected monitor/TV among them.

In a situation where even among hidden devices it was not possible to detect a TV/monitor connected via HDMI, you can try the steps described below.

No sound via HDMI on TV due to hardware problems

The second most common reason for no sound when connecting a computer to an external monitor/TV via HDMI is a hardware problem. It can manifest itself in two cases:

Installing drivers for audio output via HDMI

Another reason why there is no sound via HDMI on the TV may be the lack of drivers. Most often, this problem occurs if, when installing video card drivers, the user manually selected the components to be installed and disabled the installation of drivers for HDMI.

You can find out whether drivers are installed to output audio via HDMI to your computer in Device Manager. To do this you need:

If the list of available sound devices only includes a sound card, you need to download the drivers for the video card to your computer and install those components that are responsible for transmitting sound via HDMI. To do this, go to the Intel, NVIDIA or AMD website and download the latest video card drivers, then run their installation. At the installation stage, select manual mode and be sure to check “HD Audio Driver” among the available drivers.

Please note: The driver responsible for audio output via HDMI is called “HD Audio Driver” on the NVIDIA video card. On other maps it may be called differently.

After installing the necessary drivers, restart your computer and try connecting it again via HDMI to the TV.

Many users use the HDMI interface to connect a laptop or computer to a TV. This is a very reasonable solution that allows you to expand the functionality of the device. However, sometimes problems arise. For example, when a PC is connected via HDMI, there is no sound on the TV. What to do in such situations?

You need to start with diagnostics. Identifying the problem is not as difficult as it may seem at first. Incorrect sound transmission or its complete absence is due to several reasons:

low volume;
hardware faults;
drivers are outdated or missing altogether;
The playback device is incorrectly selected.

Absolutely every user can set up a connection. Now let's look at what needs to be done for this.

The most common and common problem. Therefore, if you are trying to determine why there is no sound on the TV when connected to a computer or laptop, check the volume levels. Take the TV remote control and check if the Mute mode is activated. The volume may be set too low.

In situations where sound is not transmitted from the laptop to the TV speakers, you need to check the volume settings on the laptop. How to do this? In the lower right corner there is an icon in the form of a speaker, click on it, and then raise the regulator up. If the speaker is crossed out, then simply click on it with LMB. Now you know the principle by which sound is output to TV via HDMI.

Checking the playback device

No sound when connected to HDMI is a common problem. Especially if the system does not automatically identify the connected device. To fix the problem, open the sound settings of your Windows operating system.

Press the Win+X key combination on your keyboard. From the drop-down list you need to select the item "Control Panel". After that, go to the section "Sound". First you need to change the default viewing mode to "Small Icons".

Right-click on the speaker icon, which is located next to the selected language indicator, next to the notifications section. You need to switch to the tab "Playback Devices". A new dialog box will display a list of available devices. If you are actively connecting headphones or speakers, you need to find other available methods. The playback method you need is called "High Definition Audio". Having found the required method, select it, and then click on the button "Default". Activation can also be carried out using a similar context menu command.

Driver problems

The lack of drivers on the computer is another reason for the lack of sound. Mostly the problem arises due to the fact that during the installation of drivers for the video card, the user disabled the installation of components for the HDMI interface. As a result, it is impossible to transfer sound from the computer to the TV.

First you need to make sure that all the necessary software components for audio output are installed. Follow the simple step-by-step instructions:

In some situations, the HDMI interface is displayed in the list, but there is still no sound when connected to the TV through this connector. The problem is that the required component is disabled. Just activate it to fix the problem.

If only the audio card is displayed in the list of sound devices, then download the drivers for the video card. Install those components that provide audio transmission when synchronizing devices via the HDMI interface.

Go to the official portal of the video card developer (Intel, NVIDIA, AMD), download the latest version of the driver, and then start the software installation process. In the driver installation menu, select manual mode. Place a tick next to the inscription "HD Audio Driver".

Remember that the software component that provides audio signal transmission through the HDMI interface is called "HD Audio Driver", but only on video cards from NVIDIA. On GPU modules from other manufacturers, the driver may be called slightly differently.

Now you know how to set up audio via HDMI if the required driver is missing. Software components must be updated periodically. Therefore, if the system offers to install a new version of drivers, be sure to agree.

Hardware problems

Another common reason why sound via HDMI does not work is hardware faults. In other words, sound is not transmitted due to a breakdown of a specific module. How to fix the problem?

First, check that the HDMI cable is working. It is possible that the cable used to synchronize the TV and laptop is broken or the contact base of the cord is damaged. The possibility of a partial wire break cannot be ruled out. If the sound disappears for this reason, use another HDMI cable.

Secondly, not all laptops and computers are equipped with an HDMI interface. Therefore, users additionally purchase special adapters: VGA-HDMI, DVI-HDMI, USB-HDMI. For example, adapters of the first two types are not capable of transmitting sound.

To avoid such problems, it is wiser to use a DisplayPort-HDMI adapter, provided that it is a high-quality device. Cheap analogues are not equipped with the special contacts necessary for sound transmission.

Connecting audio from your computer to your TV expands its capabilities, improving the sound quality of music or movies. There are several ways to do this, they all have their pros and cons, so it is necessary to give preference to one method or another, taking into account the characteristics of the equipment and its capabilities. Before you connect audio from your computer to your TV, you need to make sure that your devices have one of these connectors.

Main types of connectors

Almost all modern equipment is equipped with one of these types of connectors. They are designed for connecting external storage media, video and DVD players, as well as other digital equipment, which includes a computer.

The most used types of connectors are:

HDMI;
Wi-Fi;
RJ45;
RCA cable.

Ways to connect sound from a computer

Via HDMI connector

Audio output through this connector is the most popular, since problems and malfunctions are less likely to occur with it, and the sound quality remains good. This cord can be supplied either with some digital devices or sold separately.

There is no need to purchase an overly expensive cord, since regardless of the price, the same materials are used in its manufacture and do not change the sound quality.

To connect your TV to your computer, you first need to disconnect both devices from the power supply and then connect them using a cord. This connection method does not require any additional settings; you just need to specify the HDMI output on the TV as the audio source.

Possible problems when connecting devices

If the sound is not played, then you need to use your computer to set the TV as the sound source. To do this, right-click on the sound icon in the lower left part of the taskbar and select “Playback devices” from the pop-up menu. From the list you need to select your device, right-click on it and check the box next to the “Set as default” menu item.

When setting up, the devices must be connected to each other. If the computer does not see the TV when the HDMI cable is turned on, then you need to restart it and repeat the setup procedure again.

You also need to make sure that the video card supports audio playback via the HDMI output. Often all modern devices are equipped with this function. However, some of them include a special jumper that helps create a connector for connecting the SPDIF out connector on the motherboard with the SPDIF in connector on the video card.
You can solve the problem if you reinstall or update the drivers for the video card.

How to connect sound from a computer to a TV via a Dvi cable?

The second most popular method, which is used when it is impossible to connect via HDMI output. Connectors of this type are divided into three types: digital, analog and combined. However, transmitting sound through this connector is not as simple as with the previous one, since it all depends on the video card used in the computer, because not all of them support audio playback through the DVI output.

In the case of transmitting not only audio, but also video signals to the TV, you must use a DVI - HDMI cable or connect devices using DVI-D - HDMI adapters, and then an HDMI-HDMI cable. This complex connection system is explained by the fact that the video signal does not always pass through the DVI cable.

The disadvantage of this method is also the complex setup process compared to the previous option. To begin, in the TV menu you need to select the DVI connector as the signal source, and the computer and TV must be connected to each other.

Connection via VGA cable

This is an outdated method that is inferior to the first two in terms of ease of connection and playback quality. Therefore, it is often used in older devices where it is not possible to connect using other cables.

What problems may arise during connection?

Very often, the VGA output is already occupied by a computer monitor, so in order to connect another device you need to purchase a special adapter, and then a cord for audio playback.

Main disadvantages

VGA is not intended for audio transmission; it can only be used as an additional element, to which a special cord must be connected. This option is not only expensive, but also more complex and of lower quality compared to other methods.

How to transfer sound from a computer to a TV via WI-FI

This method places additional requirements on the TV - support for DLNA technology and the presence of a multimedia file player. Modern plasma models are equipped with this function, so this connection method can be considered as an alternative to HDMI.

Connection setup

After making sure that the TV has a built-in WI-FI module, you can start setting up.

First, you need to configure the router so that it can work in DHCP mode.

When setting up, you must assign a password that will protect the local network from unauthorized entry.

In the TV menu you need to find the “Wireless Connection” item, and then find your network and enter it using the password.
To transfer sound to a TV, you need to install a special program on your computer - a media server. This program then allows access to files and folders containing music or movies.
To switch audio from your computer, you need to open the media server and select Ethernet as the playback source on your TV.

What is the disadvantage of connecting via a WI-FI router?

When playing audio to a TV, there is a large load on the local network, which can lead to slower speeds.

Connection via RJ45

When connecting using this method, a special network cable is used, which can be found in stores under the name “twisted pair”. As in the previous method, the TV must support DLNA data transmission technology.

It also uses a router, which is configured in the same way as through a WI-FI connection. However, using this device may result in reduced speed. Therefore, it is better to give preference to an additional network card.

The setup follows the same principle as via WI-FI, but you need to connect through a media server.

How to output sound from a computer via an RCA cable

This method allows you to connect even the most outdated models of computers and televisions. Such a cable is called a “tulip”; it can have two or three sockets, each of which is responsible for transmitting a separate signal. Yellow – video, white – left channel of stereo audio signal, red – right channel of stereo audio signal.

Devices must be disconnected from power before connection. Then, you need to attach the tulip connectors to the corresponding holes (often color coded). After this, in the computer settings you need to expand the desktop to fit the size of the TV screen, and switch the TV to “Video” mode.

The most preferred methods among all those described above are connections via an HDMI cable and via a twisted pair cable or WI-FI router. It is these options that can ensure sound quality and connection reliability at the proper level.

The video shows in detail how to connect a TV to a desktop computer via HDMI and MPF. First you need to select a cable without adapters and make sure that the necessary connectors are available on the devices. Then the connectors are connected, and the TV and computer are configured.

How to connect sound from a computer to your TV

Many music lovers store digital recordings of their favorite tracks on their personal computer, but it is better to listen to them using a modern audio system. An excellent option is a home theater - surround sound, the subwoofer produces excellent low bass sound. But how to connect so that the sound goes from the laptop to the TV, and then spreads throughout the room through high-quality speakers? There are quite a lot of different ways to solve the question of how to connect sound from a desktop computer or laptop to a TV.

Main connectors

Each household appliance has connectors for connection, the main and quite often used ones are the following.

High Definition Multimedia Interface, abbreviated as HDMI. Its purpose is to transmit digital video and audio data. Recently, connecting to the World Wide Web through this port and cable has become fashionable.
Digital Visual Interface or DVI. It is designed to transmit video signals to all modern monitors and LCD TVs.
A video adapter with 15 pins or a subminiature VGA connector transmits the audio signal line by line and is used on all modern television and audio equipment.
Wireless communications or the well-known abbreviation Wi-Fi, which has become firmly established in the lives of modern youth - you can connect to it and transfer data without a cable.
Registered Jack (connector) or RJ45 is a connector for connecting a computer or laptop to household appliances.
A composite RCA connector patented in the early 1940s to switch the sound from the phonograph of that era to an amplifier. It is still used today.

All modern equipment has several connectors of various types in its arsenal to make connections easier. A DVD player, laptop or other digital media connected through these connectors is ideally combined with the TV for exchanging information.

Connection options

Today there are a huge number of cables on the market that allow you to connect different types of connectors. Each type of connection has its own characteristics.

HDMI cable

This method is considered the most popular because it rarely causes problems and malfunctions, and the quality is at the highest level. This type of cord is sometimes supplied with digital equipment, and can be purchased retail at any store.

When connecting, you need to turn off the power to the product, connect the cable to the laptop and TV. This connection does not require separate settings; only when you turn it on, specify the source of the audio signal in the TV receiver menu section.

Advice! When buying a cable, do not chase the most expensive analogue - they are all made of the same material, which does not affect the sound range.

During preparation and execution of such a connection, a problem may arise: the sound does not come through the TV acoustics. Go to the laptop settings, select the TV as the audio source, and check the “Use as default” checkbox. Also check your video card - it should support similar playback. True, many manufacturers include a special jumper in the package that helps create the connection; this should be displayed in the instructions. In order for the video card on the TV to work properly, you need to update the drivers, but only from the official website.

When setting up, both products must be connected; if for some reason the laptop does not see TV when the HDMI cable is turned on, restart the computer and repeat all the settings.

DVI

This type is used when you need to switch audio from a computer to a TV. There are three main types of such connection:

digital version;
analog method;
a symbiosis of both options.

The only problem is that this connector does not always transmit sound correctly - the reason is the video card of your PC. Experts advise using a special DVI - HDMI cable or using a DVI-D - HDMI adapter together with a cable where both connectors are identical, i.e. HDMI type. Such a complex diagram of the entire structure has a very simple explanation - the video signal does not in all cases pass freely and without changes through a cable of this type. In addition, the settings have a more complex system than with the first option.

VGA

This is quite an ancient method - it is rarely used and mainly on products with an old layout, where it is not possible to connect modern cables. This connector is always occupied on the system unit by the cord from the monitor, so you also need to purchase a special adapter and an audio playback cord.

The disadvantages include the fact that this outdated cable, connected to products, does not transmit sound according to its characteristics - it is used as an additional element. The option is considered costly in monetary terms, difficult to implement and does not have the necessary quality.

Wireless technologies

Many users often ask the question of how to transfer sound from a home computer to a TV using WI-FI and what needs to be purchased for this. Your TV must support DLNA technology - an alliance of digital networks located in the home. This modern project allows the user to solve all problems - download any applications and updates, receive and transmit video images, digital music and distribute it among compatible home devices.

Today, every flat-panel TV of the plasma model family is equipped with such functionality, so this method of data transfer is an alternative to an HDMI cable.

The settings are not complicated, but to complete them you need to buy a high-quality router that works in the DHCP system - a technology that allows you to automatically assign an IP address to any device. When you are convinced that the TV is equipped with a special module, proceed with the step-by-step setup.

We configure the router to operate in the mode In this case, it is necessary to set a very strong password (at least 10-12 characters) to protect the device from unauthorized access.
In the TV menu, look for the “Wireless Connection” section, find your network and enter it.
To transfer sound from a laptop to TV, you need to install the “media server” program on your PC/laptop, then use it to open access to the necessary virtual media in which the music is stored.
To switch sound from a PC, you need to open a previously installed program and select “Internet” as the playback source in the TV settings.

Experts attribute a significant load on the local home network to the disadvantages of this type of connection - this can affect the Internet speed.

RJ45 network cable

This type of cable is sold in retail networks as “twisted pair”. For such a connection, the TV must support data transmission technology similar to the previous option. Additionally, you need to purchase a router, which leads to a slower connection speed - you need another network card. The setup is similar to a wireless network.

PC+TV via RCA

This method is useful for connecting outdated models of PCs, laptops and TVs, to which modern cables simply will not fit. Experts call this type of connection a “tulip”; the cord may have two or three connectors, each of which is responsible for transmitting specific data or a signal. Standard marking:

yellow plug - video signal;
white is the left channel of the stereo audio signal;
red color - right channel.

Professional masters advise using the HDMI option or a wireless connection; in second place is an RJ45 cable, because only these options can provide high-quality output sound and exceptional reliability.

Some connection options can be seen in the attached video:

How to connect sound from a computer to a TV

A large number of people face the need to connect a computer to a TV every day. This is a very good opportunity, since the size of the monitor and its location do not always allow you to comfortably watch movies and other entertainment programs. In addition, the TV can be used as a monitor if the latter fails.

1 Connector types
2 HDMI
3 DVI, VGA

4 Wi-Fi, RJ45
5 S-Video/SCART

Connector types

Modern devices for connecting a computer to a TV allow you to do this very quickly, while the image and sound will be of high quality. Almost any model is suitable for such a connection, including old picture tubes. The definition of the process algorithm is directly determined by the type of connectors with which the connected devices are equipped.

The most popular interfaces (connectors) are:

HDMI;
RJ45;
Wi-Fi;
S-Video/SCART.

After a thorough inspection of the devices and identification of one or more connectors from the above list, you can begin the process of connecting the devices.

HDMI

This connector is considered the most convenient and, accordingly, the most popular. In addition to clear images, it delivers high-quality sound. To connect your computer to your TV, you just need to have a special cord with the appropriate outputs.

First, the connected means of communication are disconnected from the power supply and the cord is connected. Next, the computer and TV are turned on, HDMI is indicated as the source in the latter’s settings. The image and sound will be reproduced without auxiliary operations.

When choosing an HDMI cable, you need to understand that the materials used in its manufacture and, accordingly, the cost do not affect the sound and image quality. Therefore, it is not at all necessary to buy an expensive wire.

DVI, VGA

To connect image and sound from a computer to a TV, you can use other interfaces - DVI or VGA. The first option is more preferable. It is recommended to resort to the VGA-related method only if it is impossible to work with DVI. Often, when a user tries to connect devices using VGA, he finds that he is busy with a computer monitor. This problem can be solved using a DVI-VGA adapter, which makes it possible to make an auxiliary VGA from free DVI. Using these interfaces you can only transmit images; to connect sound to the TV you will have to buy a special audio cord.

Wi-Fi, RJ45

To connect a computer to a TV via a network connector or Wi-Fi, the latter must meet two basic requirements. The first is the presence of a multimedia player, the second is the ability to support DLNA technology. This technology gives devices the ability to exchange files online. Thanks to it, the TV can work with files directly from the computer’s hard drive, without the use of removable hard drives or flash drives.

The connection procedure via DLNA includes two steps:

connection of communication means;
installation of the DLNA server and its further configuration.

The first stage depends on whether the TV has an RJ45 network connector or a Wi-Fi module. Some models have both of these options at the same time. It is best to use a network cable to connect video and audio.

To connect the network connector of the TV to the router, you will need a “twisted pair” cable - a special cable. Finding such a cord is not difficult. However, the router option is not possible in all cases. Reason: video and sound on the TV puts a large load on the router, which leads to Internet failures (reduced speed or loss of connection). Solving the problem by purchasing a more productive, expensive router cannot be called optimal. It is better to install an additional network card, which will save money.

After connecting, proceed to install the “Home Media Server”, making the appropriate settings. To play video and sound, you need to open the “Home Media Server” on your computer and launch it. Next, you need to select Ethernet as the playback source on the TV, after which the explorer opens and the desired file is selected.

S-Video/SCART

Using this method, you can connect sound and video even to an old TV. The main condition here is the presence of an “s-video” connector on the computer, and a twenty-one-pin wide scart connector on the TV. You also need to buy an “S-Video” cord and a “SCART–audio/video/s-video” adapter.

The connection process algorithm is as follows:

The adapter is inserted into the TV connector. If there is a switch, the latter is placed in the Input position;
connection of connectors;
to transmit sound from a computer, you need to connect a special “two tulips” cord to the appropriate connectors of the adapter;
the TV turns on;
The computer turns on. After turning it on, the “Properties” item is called up, where “extend the desktop to the selected monitor”;
After switching the TV to “Video” mode, the computer desktop is visible on the screen. Next, open the file and use the mouse to move the player window onto the TV, switching it to “full screen” mode.

How to connect sound from a computer to a TV: 3 nuances

To connect sound from a computer to a TV, you don’t need to buy expensive technical devices We all love to watch the latest in the film industry, but a standard PC monitor screen is clearly not a replacement for a large flat-screen TV. That is why today more and more craftsmen connect a computer to a TV and watch movies on the big screen. In general, the connection task is quite simple, but problems with sound often arise. A trivial but very problematic question - how to output sound from a computer to a TV?

Let's first figure out in what cases you should switch the sound from a laptop or PC to a TV. So, if you have both a computer and a TV nearby in one corner of the room, then it is not necessary to switch the sound to the TV. The picture can be displayed on a large screen, while the sound will continue to flow from the computer to the speakers. It’s a completely different matter when the computer speakers and the TV are in different corners, or, what’s even more trivial, you don’t have a good audio system and the sound from the TV is much better. It is in this case that you need to connect the sound from the computer to the TV, in other words, output it to another device.

To output sound from a computer to a TV, you need to connect them together using a cable

The completion of the task depends on the following nuances:

Your software. Connecting sound on older operating systems often occurs in automatic modes. In new systems, such as Win 7,8,10, you only need to manually transfer the sound to another channel.
Connection type. Sound, like pictures, can be output to a TV through a number of methods. We will look at each option in detail later.
TV type. Depending on the model, you can make the connection active through the device menu or in automatic mode.

How to connect audio via HDMI to your TV

In general, connecting sound and pictures from a computer to a TV can occur in three main formats - via HDMI, DVI or so-called tulip cables. The very first type of cable is the newest, it is compact, easy to use and versatile - high-quality video and audio are carried through one connector. All you need to do to transfer sound from your computer to your TV is turn on the desired movie and set the appropriate settings in the menu.

Before playing the movie, you need to turn off both devices, connect one end of the cable to the HDMI socket on the computer and the other end to the corresponding socket on the TV panel.

Depending on the model of the latter, you need to either switch to HDMI mode or wait until the device itself recognizes the connected computer. Next, everything that is shown on the TV should be displayed on the TV screen.

What surprises could there be? In general, the problem with sound in almost 90% of cases boils down to one thing - you need to enable audio playback via hdmi on your computer. Otherwise, the video will go to the TV, and the sound, for example, to headphones connected to the PC.

The solution to the problem is simple:

Right-click on the sound volume icon in the lower right part of the WIN taskbar (next to the time);
Go to the “Playback Devices” menu;
Select HDMI or TV from the suggested sources (the PC often detects the device to which it is connected);
Right-click on the desired device and select it as “default device”. At the same moment, the sound will start coming to the TV.

You can buy an HDMI cable at any store that sells computers or household appliances.

If you connect your PC to your TV via a VGA cable, the procedure is the same as with an HDMI cable, but the picture quality will be slightly worse. However, in the case of connection through the so-called tulip, everything is a little more complicated. Let's look at this type of connection in more detail.

Using a tulip: how to connect a PC to a TV

In general, all modern TVs have long had connectors for connecting with new types of cables. However, if you have an old TV, you will have to connect it to the computer via the so-called “tulip” cord. It is a bundle of three cables of different colors - yellow, red and white. The cable was jokingly nicknamed a tulip because of its multi-colored appearance. So, in this bunch of “colors” the yellow cable is responsible for the sound, white for the left speaker and red for the right. This is one of the very first systems for outputting sound and video from one device to another.

The connection is as follows: insert cables of a certain color into the corresponding sockets on the TV and PC (sockets of the same color). Switch the TV to Video or RCA mode and switch the audio output on the computer via RCA.

The downside is that you won’t be able to output a high-quality HD picture through such an outdated cable, and you’ll have to forget about surround sound - a maximum of two speakers. The second problem is that most computers no longer have cinch connectors. And while sound can still be output through the tulip, for example, through a headphone or speaker jack, modern video cards do not transmit video in this way.

Everything in its place: how to switch sound from TV to computer

If you have finished watching a movie and want to return to PC mode again, you must first disconnect the cable through which the devices were connected, and then switch the computer to play sound through speakers or headphones. This can be done in the sound control manager, where you select the desired channel as the default device, for example headphones.

After connecting the cable, you need to turn on the sound in the corresponding menu

It's worth noting that it's easiest to make the switch if your computer and TV have connectors for an HDMI cable.

In this case, you won’t have to disconnect the wires for a long time and worry about settings, sound and video quality. All you have to do is unplug the cable and switch the sound source. By the way, on new Windows, most often when the cable is disconnected, the PC itself will switch to standard playback mode.

Instructions: how to connect sound from a computer to a TV (video)

Well, getting sound from a computer to a TV today is not difficult. There are several types of connecting a PC to a TV - HDMI, DVI and tulip. The first method is the newest and allows you to transmit a picture in high resolution and surround, multi-channel sound; in addition, the connection via HDMI occurs with one cable. DVI is a slightly more outdated technology, the picture quality will be average, but the connection is also made with one cable. A tulip is three cables at once, and not all PCs already have connectors of this old type. You need to switch sound from your PC to your TV in new operating systems in the sound manager menu, which can be found in the taskbar in the lower right part of the monitor screen, next to the time and date.

2 When connecting via DVI, some video card models also support audio transmission; then, when using a DVI-HDMI adapter, both video and audio will be supplied to the HDMI TV input. If you have only digital DVI on your video card (then written with the letter D), then you will not be able to connect an adapter to VGA to it, because there are no analog signals there. But if the video card has two DVI connectors, then they are written with a prefix in the form of the letter I and mean a universal port that transmits both analog and digital video signals. You can connect receivers of both analog and digital signals to such a video card. Visually, the digital-only connector is missing four pins around the horizontal slot. In universal DVI-I connectors, all contacts are present. DVI-D connectors are rarely found on modern video cards; they mostly come with universal DVI-I connectors.

3 When connecting via a DVI connector, you need to pay attention to the presence of the HDCP (content copy protection) function. Some TV models will refuse to work with this type of connection without HDCP. This is especially true for playing Blu-Ray discs.

4 If you connect your TV to your computer as a second monitor, then the monitor and TV must be configured separately. In this case, the correct screen setting would be “Extend the desktop onto this monitor.” You can display the settings of the program playing the video on the monitor, or continue working on it while watching a movie on the TV screen.

5 Blu-ray and HD-DVD discs are currently actively replacing DVDs. These discs contain films in a special film format – 24 frames per second. Moreover, if the computer uses a frequency of 50-60 Hz, the image “slows down”. The picture will be as clear as possible if you switch the video card to a refresh rate of 24 frames per second. However, this can only be done if the TV supports 24p mode.

Connecting audio from a computer to a TV

1 To get sound from AMD/ATI video cards, in the “Sounds and Audio Devices” control panel settings of your operating system (WinXP), you need to select the default audio output device “ATI HD Audio rear output”.

2 When connecting some video cards, there may be no sound with an HDMI-HDMI cable. There may be no sound on the video card itself, and you need to connect sound to the video card from the motherboard from “SPDIF out” (motherboard) to “SPDIF in” (video card) using a special short cable (must be supplied with the video card). After that, connect the HDMI cable to the HDMI ARC input of the TV, and in the computer settings “Start-Control Panel-Sound-Digital Audio” make S/PDIF used by default. Uncheck the “disable digital output” checkbox. And carefully read the manual for the motherboard and video card.

3 If the sound quality is poor, check the sound card or player settings for stereo or 5.1 or some other sound output. Try changing the output from one mode to another.

4 When connected via DVI, sound can be supplied from the miniJeck on the computer to the “Audio DVI in” input, not to be confused with the Audio in input for a composite signal. If after this there is no sound, then look at the sound settings on the TV, maybe you need to switch the input.

5 In some models of sound cards, in rare cases, in order to supply sound to the TV, you need to pull out the speaker and headphone connectors from other connectors.

6 When connecting a video signal via a DVI-HDMI cable, some TV models will also take sound from the HDMI input, but the computer does not produce sound via DVI and, according to all the rules, the user connects the sound with a separate cable. So, to play sound, you may need to additionally specify in the TV menu that for a given HDMI input you need to take sound from another input.

7 When using DVI-HDMI adapters, it is better to use it on the computer side and connect an HDMI-HDMI cable to it. This is the case when using video cards that mix the audio signal into the DVI using S/PDIF. If you use a DVI-DVI cable and there is already a DVI-HDMI adapter on the TV side, then the sound may not pass through, because there are three types of DVI connectors (digital, analog and combined) and the cables are different and where the video card mixes the sound, to which We don't know the contacts. Or maybe the cable just doesn’t have the contacts that are needed to transmit sound? The DVI-I dual link cable has the most complete set of conductors inside, but the rest need to be looked at.

8 Some TV models have a menu item “Audio HDMI”. When enabled, audio will only be taken from the HDMI input when an HDMI cable is connected. You need to know this if you are using a DVI-DVI cable, and there is a DVI-HDMI adapter in front of the TV and the sound is supplied via a separate cable. So, with this connection and the “Audio HDMI” item is active, there will be no sound on the TV. When you disable this menu item, the sound should work.

9 Sound, if not on the video card, is taken from the output of the sound card.

10 It happens that the sound does not pass through due to incorrect input/output settings in the sound manager on the computer. One inconspicuous item in the menu can ruin everything, look carefully at all the settings of the video card, sound card and player.

11 In Windows XP, problems often arise with the SPDIF setting. The fact is that in this OS the digital output is not displayed as a separate audio output device. Therefore, where the sound goes depends on the driver. As a rule, analog and digital outputs are either duplicated, or when a digital output is connected, the analog one is disabled.

12 ATI video cards already have their own sound controller built-in, so no other sound devices are required. In case of audio output via the DVI connector, you must use a proprietary DVI->HDMI adapter. Check the availability of the adapter in the kit directly at the store where you make the purchase - equipment may vary! You must use the adapter that comes with your video card. Left adapters, as well as DVI->HDMI cables, will not work. The "correct" adapter contains a chip with a number sewn into it.

13 NVidia mobile video cards of the 8xxx series and higher support audio transmission via HDMI according to the same principle as ATI discrete video cards, i.e. have their own sound controller, which is defined by the system as a separate audio output device (Realtek HDMI Output). As for the supported formats, it is reliably known about the output of 5.1-channel audio.

14 If you are sure that you have configured the system correctly, connected the bridge in NVidia, installed the driver for ATI, but the sound still does not appear, open the instructions for the TV and check whether you need to specifically select audio reception via HDMI in the TV menu, and what formats digital audio supported.

15 If we want the sound to go to the TV only when watching a movie, then select the analog output as the default device (as usual). And in the settings of your player, through which you watch movies on your TV, select SPDIF (for NV) or Realtek HDMI Output (for ATI), respectively.

Acts as a monitor. Connecting a laptop or personal computer to a TV expands the capabilities of the computer and improves the quality of movies and music. There are several ways to do this, but you need to consider the characteristics and capabilities of the technology. The most universal way is to connect via an HDMI cable, since problems rarely arise with it, and almost all TVs have an HDMI connector. But one problem may arise here - there is no sound on the TV, and the audio still comes from the laptop speakers or computer speakers, although it should come from the TV. How to properly adjust the sound on your TV? This problem can be solved quickly and easily: just change certain settings on the computer, and for Windows 7, 8 and Windows 10 these settings are very similar. Let's consider possible reasons for the lack of an audio track and options for solving this problem.

Setting the sound on the TV when connected via HDMI.

If, when connecting a computer to a TV, there is no sound at all, even from the PC speakers, then the reason may be trivial - the sound is simply reduced to a minimum. Check:

The sound level of the TV itself.
Volume on a laptop or computer.
Check the silent mode button on the remote.

This is especially true if the equipment worked before.

IMPORTANT. Make sure you connected the HDMI cable. The VGA cable does not transmit an audio signal.

2. Check playback devices

On modern operating systems such as Windows 7, 8, 10, when you connect a laptop or any other device to a TV, the sound is played automatically on the connected device. The OS itself determines the connected audio playback device. However, sometimes this may not happen, and you need to manually select the appropriate device on your PC. For this:

We connect the computer using a cable to the TV (and do not disconnect it during all the steps).
Find the notification panel, the speaker icon and right-click. You need to select "Playback devices".

ATTENTION. In certain Windows 10 updates, you must first select Open Sound Options and then open the Sound Control Panel.

The window that appears will list all available playback devices - TV, laptop speakers, headphones (if available). Please pay attention to which device is used. You need to select your TV (or any connection that has HDMI in its name) and check the “Use as default” checkbox. Apply the settings.

IMPORTANT. If the TV is displayed in the “Playback devices” column, but marked “Not connected” (or “Not active”), then you need to restart the PC without disconnecting the HDMI cable.

This usually helps solve the problem. But there are special cases when the active devices are missing something related to the HDMI connection. Try clicking on an empty space and checking the “Show hidden and disabled devices” checkbox. If the sound still does not work, let's try the following ways to fix the problem.

3. Check the controller

If the TV still does not appear in playback devices, then the problem may lie in the High Definition Audio controller. To check the activity of the controller, do the following:

Launch the device manager and go to “System devices”. Let's see if the controller is turned on. If there are any icons next to it, we try to turn on the controller by right-clicking.
Open the properties and check how the device works. If there is no indication that the device is working normally, you can try turning it off, restarting the computer, and turning it on again.

IMPORTANT. do not remove the controller! There is a possibility that the system will not be able to install it again automatically, and then the sound will disappear completely.

Check the “Audio inputs and outputs” tab. A device that has no audio may appear there. All adapters must be active.
If the methods listed above do not work, try opening “Sound, game and video devices”. There, depending on your video card (AMD or NVIDIA), you can check the operation of the adapters.

4. Checking the drivers

If you have tried all available devices, and there is still no sound coming from the TV, then the problem may lie in audio output drivers that are either installed incorrectly or not installed at all. Perhaps, when installing drivers for your video card, you manually selected the necessary components. To fix this, do the following:

We go to the device manager (or open the desired window by clicking on the “Start” button for Windows 10).
Find “Sound, game and video devices”.
Select “View” and turn on the display of all hidden devices.
We look at the number of displayed connections. If a device with HDMI in its name is available but disabled, then right-click on it and click “Enable”. If in the list you see only the sound card of the laptop itself, then move on.
Download or update video card drivers using the official website of your video card manufacturer. Before installing drivers, double-check that the HDMI audio driver will be installed.

ATTENTION. You can take the risk of updating your drivers using DriverPack Solution. This method is not reliable, but sometimes it can help.

Reboot the computer.

If problems arise with installing drivers, then there may be problems in the operation of existing video card drivers. In this case, you can try removing all previously installed video card drivers and reinstalling them.

5. Not a single method solved the problem.

If none of the above options help, it makes sense to try diagnosing the problem. To do this, right-click on the speaker icon and select “Diagnostics sound problems.” The OS may be able to detect and fix the problems. Double-check if the sound disappears. If it still disappears, try repeating the steps above.

We hope you were able to set everything up! If not, write in the comments about your problem, as well as possible solutions that we forgot to mention. Good luck!
