How to make sound from a computer to a TV

Why is there no sound via HDMI on a TV when connecting a laptop (PC) on Windows 7 and Windows 10

I have already prepared several instructions for connecting a TV to a computer on an HDMI cable, and noticed that there is one very popular problem that many are faced with. The problem is that after connecting the TV to the computer, or laptop, there is no sound on the TV. That is, the sound is not played through the HDMI cable, but continues to sound from the speakers of the laptop, or the speaker system.

We know that through HDMI cable, sound transmitted. So he should sound from the speakers of the TV. And as a rule, the sound on the TV is much better and better than on the same laptop. Therefore, it makes sense to tune the sound through the HDMI cable on the TV. When I wrote the instructions for the connection, I myself came across a problem when there was no sound on the TV. But, this problem is solved very simple. You just need to change some settings on your laptop, or PC. Over, in Windows 7 and Windows 10, these settings are almost the same.

I immediately give links to detailed articles on connecting a TV by HDMI:

By the way, in these articles, I wrote about problems with sound. Everything is described in detail there. In one article on the example of Windows 7, and in the second, for example, Windows 10.

How to connect two TV to PC with one HDMI part

If there is only one HDMI connector on the video card, the first and easiest option for connecting two TVs will be the use of a video signal branch of, for example, Telecom Ta653.

One end of the branching is connected to the HDMI output of the PC video payment, and in the other two, HDMI cables are inserted to two TVs.

Video.Signal branch for connecting to a computer two TV

However, such a decision has an obvious drawback associated with the fact that the same image will be displayed on two connected TVs.

You can expand the capabilities of PC when transmitting a video signal if you use additional connectors located on the video card.

Many modern video cards include two or more connectors for connecting external sources of signal display. Usually these are sets of connectors VGADVI, VGAHDMI and T.D.

For example, if a video payment has a DVI-HDMI branded adapter as well as HDMI-HDMI cable, or a separate DVI-HDMI cable, this will make the video and sound on TVMI.

DVI-HDMI cable

Reference! Not all video adapters can work in the image transmission mode through several channels at the same time. In these cases, one of the TV when viewing will be inactive.

If the sound from the laptop on HDMI is still not played on the TV

If both methods have not helped, while in the reproduction devices the desired point is accurately set, I recommend paying attention to:

  • Once again. Check the tV settings.
  • If there is such an opportunity, try another HDMI cable, or check whether the sound will be transmitted to the same cable, but from another device, and not from the current laptop or computer.
  • In the event that an adapter or adapter on HDMI is used to connect via HDMI, the sound may not be possible to get to work. If VGA or DVI is used on HDMI, then definitely not. If DisplayPort is HDMI, then it should work, but there are no sounds on some adapters in fact.

I hope you managed to solve the problem, if not. Describe in detail what and how is happening on a laptop or computer when trying to take steps from the leadership. Perhaps I will be able to help you.

Stereo mixer in Windows 10: Sound output to two devices at the same time

Open sound parameters (by pressing the corresponding icon in the trias with the right mouse button) and go to the sound control panel.

In the “Sound” window, we check that the Dynamics device is in the status of “default device”. If this is not the case, then click on them with the right mouse button and select “use by default”. Also, note that I have a TV connected by HDMI there (in my case, this is a monitor with built.In speakers, this is not important) and it is in the status of “Ready”.

We go to the “Record” tab. There should be “stereo mixer”. If it is dull and it is written “disabled” near it, then click on it with the right mouse button and select “Turn on”. Also, if it is not used by default (there is no appropriate inscription near it). Then click with the right mouse button and select “use by default”. Then click again and open the “properties”.

HDMI No Sound in Windows 10 When Connect to TV. No HDMI Audio Device Detected FIX

In the new window, opening the “Listen” tab, make sure that near the item “Listen from this device” there is a checkbox. From the menu, select the device to which you need to display the sound from the computer. So the speakers are used by default, and we need to choose the second device. In my case, this is a TV (you will have another name). It can also be Bluetooth nashers, a column, maybe some more device.

After clicking on the “apply” button, the sound began to play simultaneously from the speakers (laptop speakers) and TV. Check the volume level on the TV, or headphones (column).

To turn off the sound from the second source, just turn off the stereo mixer, or turn off the device. The settings are saved. When we adjust the sound in Windows settings, it is simultaneously adjustable on both devices (in my case, on the columns and speakers).

The main methods of how to connect sound to TV from a computer

There are several ways to connect the sound to the TV from the computer, the choice of optimal depends on the equipment of the equipment with certain connectors.

The main method is how to connect the sound to the TV from the computer. When transmitting sound, difficulties very rarely arise through this cable, and the quality of the audio signal is very high. The most optimal option for new TV models. HDMI cable often goes in a set with various television and audio equipment, you can also purchase it separately.

This option does not require additional settings, just select HDVI output in TV as source of sound.

But, if there is no sound, it is recommended to set the TV on a personal computer, as the main source of sound.

  • The right mouse key select the sound icon, then select the “Equipment for playback” tab from the device that appears to select your technique.
  • Click on the selected version with the computer mouse and install the checkbox next to the default tab.

The procedure is performed with equipment connected to each other. In the event that the NDMI cable is connected to the devices, but the PC does not see it, then you should reload it.

Another popular way to switch the sound from a personal computer to TV. There are three types of connectors:

In this type of settings, a computer video card must support the sound format through DVI. Scheme:

This scheme of displaying sound from a computer to a TV is recommended only if the device cannot transmit the signal through DVI. This method is usually used on outdated equipment.

The frequent phenomenon that the VGA connector is busy with the PC screen, so switching can only be performed using a special adapter, and then the VGA cable is joined.This transmission option is considered the most difficult and expensive.

This method is possible only on condition that the TV has DLNA support, a multimedia player is also needed. All modern panels support DLNA, so this method can be considered an alternative to sound transmission through HDMI. Thanks to this option, the connected screen works directly with PC files. Scheme:

  • Make sure that the plasma panel has a module for distribution via wi-fi connection.
  • Turning on the devices.
  • Installation and setting of the DLNA server.
  • In the tinctures of the TV menu, select the “Wireless connection” tab.
  • To translate the sound to TV, you need to download a special computer application called media server.
  • To convey an audio sound, the user must open this program and select “Ethernet”.

The best option is to transmit a sound signal to old TV models. Often such a cord is called “tulip”, it has three branches, the red nest is responsible for the sound on the right, the yellow is the left sound, and the white. The video signal. Scheme:

  • Disable all devices from power supply.
  • In PC settings, expansion of the computer monitor should be expanded by the size of the television screen.
  • Put the TV into “Video” mode.

Of all the listed methods of sound transmission, the best are HDMI and Fi-Wi the best. Since they provide high sound quality and reliable operation of the equipment.

Ways to connect sound from a computer

Through the HDMI connector

The removal of sound through this connector is the most popular, since problems and problems arise less often, and the sound quality remains good. This cord can be delivered both to some digital devices, and will be sold separately.


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

No sound on tv from pc hdmi. How to solve

To connect the TV to the computer, first you need to turn off both devices from power, and then attach them using the cord. This connection method does not require any additional settings, it is enough to indicate on the TV as a sound source HDMI output.

Possible problems when connecting devices

  • If the sound is not played, then it is necessary to set the TV as a sound source using a computer using a computer. To do this, pressing the sound icon in the lower part of the taskbar with the right mouse button, select the “playback device” item from the pop.Up menu. You need to select your device from the list, press it with the right mouse button and put a mark opposite the menu item “Use by default”.


At the time of the settings, the device must be connected to each other. If the computer does not see the TV, when the HDMI cable included, then it is necessary to restart it and repeat the settings procedure again.

  • It is also necessary to make sure that the video card supports sound reproduction through 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 SPDIF OUT ”on the SPDIF In system board on the video card.
  • You can solve the problem if you reinstall or update the drivers to the video card.

How to connect sound from computer to TV via DVI Cable?

The second most popular method that is used when it is impossible to connect via HDMI output. The connectors of this species are divided into three types: digital, analog and combined. However, with the transmission of sound through this connector, not everything is 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 the sound reproduction through the DVI output.

In the case of transmission of not only sound, but a video signal to the TV, you must use a dvi-HDMI type cable or connect devices using DVI-D-HDMI adapters, and then HDMI-HDMI cord. Such a 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 a complex setting process compared to the previous option. To begin with, in the TV menu, you need to select a DVI connector as a signal source, while the computer and TV must be connected to each other.

Connecting via VGA cable

This is an obsolete way that loses the first two in terms of simplicity of connection and quality of playback. Therefore, it is often used in outdated devices, where it is impossible to connect through other cables.

What problems can arise when connecting?

Very often 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 to play sound.

The main disadvantages

VGA is not designed to transmit sound, it can only be used as an additional element, to which it is necessary to connect a special cord. This option is not only costly, but more complex and less high.Quality compared to other methods.

How to convey the sound from a computer to a TV via wi-fi

This method puts forward additional requirements for the TV. Support for DLNA technology and the presence of a player of multimedia files. Modern plasma models are equipped with such a function, so this method of connection can be considered as an alternative to HDMI.

Connection configuration

After making sure that the TV is equipped with a built-in Wi-Fi module, you can start setting up.


When setting up, it is necessary to assign a password that will protect the local network from an unauthorized entrance.

  • In the TV menu you need to find the item “Wireless connection”, and then find your network and enter it using a password.
  • To transfer the sound to the TV, it must be installed on a computer a special program. Media server. Then, using this program, access to files and folders containing music or movies opens.
  • To switch the sound from the computer, you need to open a media server, and select Ethernet as source of playback on the TV.

What is the lack of connecting via Wi-Fi router?

When playing sound on the TV, a large load on the local network is created, which can lead to a decrease in speed.

Connection via RJ45

When connecting this, the method uses a special network cable, which in stores can be found under the name “twisted pair”. As in the previous method, the TV should support DLNA data transfer technology.

Checking the High Definition Audio controller

If there is no sound with HDMI connection, and the PC in the “playback device” section does not display TV, then it is worth making sure that it is not disconnected. To do this, you need to find a subsection with system devices in the device dispatcher and click on the High Definition Audio controller in it. Among the actions that can be performed with him to “turn on”. If the node is turned on, you can try to turn it off, restart the PC and try to turn it on again. Also, it will not be superfluous to update this equipment.

If the node is turned on, you can try to turn it off, restart the PC and try to turn it on again

In the open dispatcher of the devices, it is also worth entering “Sound, game and video devices”. There may be a similar controller from AMD or NVIDIA. If it is, then we repeat the actions described above. The last point that will not be superfluous to check. “Audio and video outputs”. The TV can be displayed here, in this case, try to turn it on or disable/restart PC/turn on.

Connection options

Today, a huge number of cables are presented on the market, which allows to combine various types of connectors. Each type of connection has its own characteristics.

HDMI cable

This method is considered the most popular, because with it problems and malfunctions are quite rare, the quality is at the highest level. The cord of this type sometimes comes with digital technology, and in the retail network it can be purchased at any store.

When connecting, you need to de.Energize the products, connect the cable to the laptop and TV. This connection does not require separate settings, only when you turn on the television receiver in section, indicate the source of the sound signal.

Advice! When buying a cable, do not chase the most expensive analogue. They are all made of one material that does not affect the sound series.

During the preparation and execution of such a connection, a problem may arise: the sound does not go through the acoustics of TV. We go into the laptop settings, select the source of the sound signal TV, put the box “Use by default”. Also check the video card. It must support a similar reproduction. True, many manufacturers introduce a special jumper in the complete set that helps to create a connection, in the instructions this should be displayed. In order for the video card on the TV to work properly, you need to update the drivers, but only from the official site.

When setting up, both products should be connected if the laptop for some reason does not see TV when the HDMI cable is included-reboot the computer and repeat all the settings.

This variety is used when it is necessary to switch the sound series from the computer to TV. There are three main types of such a connection:

But with the help of this connector, the correct sound transmission does not always pass. The reason is in the video card of your PC. Experts advise using a special DVI-HDMI cable or use the DVI-D-HDMI adapter along with the cable, where both connectors are identical, t. E. Type HDMI. Such a complex scheme of the entire design has a very simple explanation. The video signal is not in all cases freely and without changes passes through the cable of this type. In addition, the settings have a more complex system than in the first option.

A rather ancient way. It is rarely used and, mainly on products of the old layout, where there is no way to connect modern cables. This connector is always occupied on a system unit with a cord from the monitor, so you also need to purchase a special adapter and a sound row player.

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

Wireless technologies

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

Today, each flat TV family of plasma models is equipped with such functionality, so this method of data transmission is an alternative to HDMI cable.

The settings are not difficult, but for their implementation it is necessary to buy a high-quality router working in the DHCP system-a technology that allows you to automatically assign to any IP address devices. When you were convinced that the TV is equipped with a special module, proceed to the phased setting.

  • We set up a router to work in mode at the same time, it is necessary to install a very reliable password (at least 10-12 signs) to protect the device from extraneous penetration.
  • In the TV menu, we are looking for the “Wireless Connection” section, we find our network and enter it.
  • To translate the sound from a laptop to TV, you need to install the Media Serrender program to your PC/laptop, then use it to open access to the right virtual media in which music is saved.
  • To switch sound with PC, you need to open a previously installed program and select the Internet in the TV settings as source of playing a “Internet” play.

Specialists include a significant load on a local home network to the disadvantages of this type of connection. This may affect the speed of the Internet.

Network cable RJ45

This type of cable in the retail network is sold as “twisted pair”. For such a connection, the TV must maintain a data technology similar to the previous version. Additionally, you need to purchase a router, which leads to a slowdown in the connection speed. You need another network card. Settings are made similarly to a wireless network.


This method is useful for connecting outdated PC models, laptops and TV, which modern cables simply will not work. Experts call this type of “tulip” connection, the cord may have two or three connectors, each of which is responsible for the transmission of specific data or signal. Standard marking:
