Sometimes when watching movies on TV, sound Computer speakers may not be enough. This can be corrected by allowing the TV, in addition to the image, to also output sound, using the full power of its speakers.

You will need

• Soldering iron, one or two RCA connectors (tulip), one TRS 3.5 mm connector (mini-jack), two-core shielded cable, knife.

Instructions

Most modern ones, in addition to HDMI, S-Video and SCART, have RCA connectors, which are popularly called “tulips”. It is through them that we will transmit sound from . If it supports stereo sound, then you will need two such connectors (red and white connectors), if mono, then only one (white connector).

On a computer, the audio output can be located either on the motherboard or on a separate one, if installed. This nest is usually light green in color. If the sound is motherboard if it is routed to the front panel of the case, then this socket is located in the front, otherwise it is in the back. It is connected to a 3.5 mm TRS connector, which is usually called a “mini-jack”.

Take a cable of the required length and strip it on both sides with a knife. Be careful not to damage the wire when cutting the insulation. Gather the screen braid on one side and twist it into a pigtail. In order for the soldering process to go better, the wires must first be tinned. Disassemble the mini-jack and solder the screen to the large petal, and two wires to the two small petals. Now put the connector back together.

Now it's time to work on the other end of the cable. If you need a mono signal, then solder the screen to the outer part of the “tulip”, and both signal wires to the central contact. Before you solder the connector to the wire, be sure to put the screw-on part of the connector on it. If you have stereo sound, then the screen needs to be divided into two parts and soldered each part to external contact" ". One signal wire is soldered to the central contacts of both “tulips”. Assemble the connectors and connect the cable to the corresponding connectors and . The sound will now be transmitted through the TV speakers.

If your favorite way to spend free time- these are computer games or online viewing movies, undoubtedly one day it occurred to you that the TV screen would provide you with a larger, more spectacular and more convenient picture.

Today, many people connect a TV to their computer to use it as an additional monitor. Almost everything modern televisions provide such a possibility, so there are few problems when connecting, but they still happen.

Connection via HDMI cable

If earlier a special cable with several “tulip” connectors was used to connect a TV to a computer, today its role is perfectly fulfilled by an HDMI cable, which provides maximum high quality screen image.

The connection itself is not a problem, because HDMI connectors are available on any TV and on any computer device– stationary system unit, laptop and . You just need to connect the appropriate cable connectors to them, and the job can be considered done.

Sound problems

But here sometimes troubles begin: if the image appears on the TV screen without problems, then difficulties arise with sound transmission. Or rather, there is sound, but it comes from the computer speakers, while on the TV the sound remains muted.


Of course, you can leave everything as is, but if you want to achieve complete comfort, you need to complete the connection. First of all, make sure that the sound on your TV is actually not coming from the computer, and is not turned off. To do this, try adjusting the volume with the TV remote control.

After making sure that everything is in order, look at the computer’s volume slider - perhaps it is set to zero, and the sound does not reach the TV speakers for this very reason.

Audio Sync

As you know, in the lower right corner of the computer screen on the taskbar there is an icon sound devices. Sometimes it is used to increase or decrease the volume or to adjust the sound. Let's use it this time too.

Click right click mouse over the speaker icon. In the menu that opens, select "Playback Devices" and open this tab. All available audio devices should be listed there, among which the TV should be on the list.

All you have to do is select it and right-click to open it context menu, in which check the box next to the item "Use as default" . In most cases, this is enough for the sound to be reproduced normally by the TV speakers.


Some the situation is more complicated, in which the TV is not displayed in the audio device menu, i.e. the computer simply “does not see” its speakers. In this case, as in many others, it can help you full reboot. Without disconnecting the HDMI cable, .

Once the reboot process is complete, open the sound menu again and make sure the TV appears in the list. If it is inactive, proceed as described above - set its status "Use as default" .

Sometimes, in order to resolve a device conflict, it is necessary to disconnect all other audio peripherals such as speakers and headphones from the computer. Otherwise, a device priority conflict occurs - the computer cannot choose which one to use to play sound. When extra devices disappear, the situation returns to normal.

The possibility of a cable defect cannot be ruled out - if some of its connectors are oxidized, or one of the wires is broken, sound reproduction becomes impossible. In order to set up the system, you will need a fully functional, tested HDMI cable.

If your computer has a video card installed NVIDIA, the sound problem may lie in its settings. These video cards have their own sound controller, the operation of which will have to be regulated through the sound menu of the player you use to play movies.

Many music lovers store digital recordings of their favorite tracks on personal computer, but it’s better to listen to them using a modern audio system. An excellent option is 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 in various ways, allowing you to solve the question of how to connect sound from a desktop computer or laptop to a TV.

Each Appliances has connectors for connection, the main and quite often used of them are the following.

1. Multimedia interface high definition , abbreviated as HDMI. Its purpose is to transmit digital video and audio data. IN Lately it has become fashionable to connect with worldwide network through this port and cable.
2. Digital visual interface or DVI. It is designed to transmit video signals to everything modern monitors and liquid crystal TV.
3. Video adapter with 15 pins or subminiature VGA connector transmits the audio signal line by line, used on all modern television and audio equipment.
4. Wireless connection 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.
5. Registered Jack (connector) or RJ45 is a connector for connecting a computer or laptop to household appliances.
6. 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. Connected through these connectors, or another digital media, is ideally combined with the TV for information exchange.

Connection options

Today on the market there is great amount cables, allowing you to connect Various types connectors. Each type of connection has its own characteristics.

This method is considered the most popular because it rarely causes problems and malfunctions, and the quality is at the highest level. A cord of this type 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 individual 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: Go to the laptop settings, select the TV as the audio signal source, and check the “Use as default” box. 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.

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 cable DVI type– HDMI or use a DVI-D to HDMI adapter together with a cable where both connectors are identical, i.e. HDMI type. Such complex circuit The whole design 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

Quite an ancient method - it is used rarely and mainly on products of the 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 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, how is the sound with home computer transfer to TV when WI-FI assistance and what you need to purchase for this. Your TV must have support DLNA technologies - 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, music digital format 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 perform them you need to buy a high-quality router, working in DHCP system- 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.

1. We configure the router to operate in the mode. In this case, it is necessary to set very strong password (at least 10-12 characters) to protect the device from unauthorized entry.
2. In the TV menu, look for the section “ Wireless connection", we find our network and enter it.
3. To transfer sound from a laptop to TV, you need to install on your PC/laptop media server program, then use it to open access to the necessary virtual media in which the music is stored.
4. 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 the disadvantages of this type of connection to the significant load on the local home network– this may affect Internet speed.

RJ45 network cable

This type of cable in the retail network is sold 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 one LAN 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 connection type "tulip"", the cord may have two or three connectors, each of which is responsible for transmitting specific data or signal. Standard marking:

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

Professional craftsmen advise using the HDMI option or connection wireless type, 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:

Have you decided to watch the downloaded movie not on a small monitor screen, but on a large television? Then you will need an HDMI cable, thanks to which the picture can be broadcast to big screen, and the sound comes from good and powerful speakers.

However, when connecting, you can periodically notice that the picture is transmitted, but the sound comes only through the computer speakers. What should I do if there is no sound through the HDMI cable on my TV?

Correct connection

First, you need to check if you installed everything correctly. It often happens that not there is a sound via HDMI to your TV because you chose the wrong cable or the wrong ports. The following errors often occur:

Inappropriate ports were used by mistake

The cable is not the same

Usually on devices they write why certain holes are installed in them. Therefore, in this case, we can only wish to be more attentive to such things.

As for cables, VGA does not transmit sound at all.

Setting up the computer

If you did everything correctly, but the sound on the TV via HDMI does not work, you should try to check whether the computer considers the TV a system for playing sound. To do this, go through the “Start” menu to the “Control Panel”, find “Hardware and Sound” there and in the “Sound” window open the “Playback” tab. If you don’t find anything there, the list is empty, then right-click to bring up the menu and turn on “Show disabled devices” and “Show remote devices».

After this, your TV model should appear in the list. Click on it and turn off other devices. This should help resolve the issue where the audio on your TV is not working via HDMI.

If this method didn't help

If you have done everything described above, but there is no sound on the TV via HDMI, you should try to check the functionality of the cable or TV itself. Updating your sound system drivers will also help, which you can do on the official websites of the companies.

I hope we have helped you understand how to transmit audio through an HDMI cable.

It is unlikely that anyone will argue with the fact that the spacious screen of high quality digital TV better suited for watching movies high resolution And computer games than a small laptop or desktop PC monitor.

This is why many users connect these two devices special cable, capable of transmitting pictures and sound.

And here some people have a problem - they don’t know how to set up sound via HDMI. If you also encounter this problem, use the tips from this article.

Reasons why there is no sound on the TV

• The computer or laptop does not recognize your TV's speakers as a playback device and continues to play through the speakers/headphones connected to the sound card.
• Physical malfunction of the equipment. May be damaged itself sound card, connectors on it, a connector on the TV and even an HDMI cable (the latter are often not supplied best quality, with a defective contact base).
• Incorrect TV and PC settings. In order for the sound to be transmitted without distortion, everything needs to be configured correctly on both sides. The connection does not always work with standard settings.

Setting up and testing sound in Windows

Before you can play sound via HDMI (or any sound, really), you first need to install specialized software on your system.

Usually, modern versions Windows is installed by default necessary drivers, but more fine tuning is possible only after installing “native drivers” on the sound card.

Usually suitable version comes included on a disk with motherboard, if the card is integrated. As a last resort, you can download the current installer from the manufacturer's website.

When the driver is installed, check it - you can launch a movie or music track, making sure the quality of the signal is transmitted and that it is supplied to all speakers of the connected device.

In the driver settings (the manager shortcut is usually located on the taskbar, near the clock), set desired type audio system and play with the equalizer sliders to achieve a comfortable sound level.

Checking the sound on your TV

This may seem trivial and obvious, but the user should check the TV itself by turning on a channel or playing a file from another connected device.

Modern TVs are smart devices— the number of sound settings they usually have is not limited to the volume control.

Often the computer is not automatically detected as a signal source, so you need to go to the audio options menu on the TV itself and select HDMI (computer) as the source.

Also make sure that in the settings profile all volume parameters are set to acceptable values ​​and that no silent mode is enabled.

If there is a Smart mode, in which the TV itself controls the sound level, it is also better to turn it off.

Checking the health of the sound driver

If you cannot play sound via HDMI on your TV, this may indicate a missing or faulty driver installed on your computer.

Diagnosing this problem is quite simple, you just need to follow the following path:

Availability exclamation point opposite the component name indicates a malfunction, and if the device is not in the list, that the driver is not installed at all. The problems listed above can be solved quite simply.

Installing the HDMI Driver

Many users, when installing drivers for a video card, uncheck the boxes next to optional components, and then are sincerely surprised why HDMI does not transmit sound to the TV.

For example, the manufacturer Nvidia has additional software called “HDMI Audio Driver(HD Audio Driver)".

Don't have to do it complete reinstallation software– just download the required component separately from the manufacturer’s website. AMD also has similar solutions with their ATI Radeon cards.

Alternative option- usage third party software like Driver Booster, Driver Pack Solution and their analogues.

Such programs scan the system, identify connected devices and offer automatic mode download drivers compatible with computer hardware.

This is one of the best and simplest options.

Update sound drivers

To update drivers already installed on the system specific device, you can use the task manager (it was already mentioned above how to get into it).

Find the one you need in the list of sound devices, right-click on it and select “Update” from the drop-down list.

A similar function is present in driver management programs.

On the other hand, it is better to spend a little more time and produce clean install, completely removing old drivers.

This will help avoid transferring old settings and possible problems on new version. Remove the software responsible for sound not only from the Control Panel

Checking device functionality

When there is no doubt about the serviceability of the drivers and equipment, all that remains is to make sure that they are configured correctly:

It also happens that it is not displayed in the list of playback devices.

Then it can help to right-click on any of the available devices in the list and check the box next to “show disabled and disconnected devices.”

If the manipulations help, simply turn on the desired speakers, and turn off the current ones to avoid conflict.

The SDMI standard is not compatible with older TVs and video cards.

Many people mistakenly believe that to successfully connect a TV to a computer they will only need to buy a cable with HDMI-DVI adapter or HDMI-VGA, but in this case only the image will be transmitted.

But with the standard Display Port It is quite possible to reproduce sound via HDMI, since it has all the necessary contacts.

In the video driver settings there are also items responsible for connecting audio devices via HDMI.

Nvidia, for example, has a “Digital Audio Installation” item in its Control Panel. Here you can select your TV as the output device.

So, check not only the parameters sound drivers audio card, but also video card settings.
