Perhaps the simplest and most inexpensive option for outputting sound to a TV is to connect using a stereo cable with a 3.5mm jack on both sides. Such cables are often included with many models of MP3 players, and they can be used not only to connect to a TV, but also to play sound through a stereo or car audio system.
The cable connects to the headphone jack on the computer, and on the TV to the Audio IN jack, which is similar in appearance to the headphone jack. After this, the TV switches to A/V mode and the sound from the computer will be heard through the TV speakers. If there are several A/V modes, you should enable sound playback on the computer and use the selection method to determine the desired A/V mode.
Another connection method requires both devices to have an HDMI interface connector and an appropriate cable. HDMI connectors can be found on TVs and computers released in the last few years.
Connect your computer and HDMI TV cable and switch the TV to playback mode external source. There may be several modes and you will have to determine the one you need using the selection method using the button on the remote control, which usually has the designation A/V or a square icon with an arrow. A successful connection can be determined by the appearance of sound from the computer in the TV speakers.
When connecting via an HDMI interface, set the image output mode to an additional monitor in the properties of the computer’s graphics card, and you will be able to output not only sound but also image from the computer to the TV.

Speakers built into TVs often have mediocre sound quality. You can improve it by connecting external speakers. They can be connected in two ways: through an amplifier or directly.
Instructions
In order to use the first method, you will need TV maintenance skills and impeccable knowledge of safety regulations. Turn off the TV, open it (do not subject it to impacts, so as not to break the picture tube or LCD matrix), and then, without touching the picture tube, the high-voltage wire, as well as parts of the power supply, video amplifier, backlight power converter (in an LCD TV) , line scan (and in a tube TV - any other parts), unsolder the wires going to the speaker, extend them with a long cable, and then lead them outside the TV so that they do not pass near any high-voltage circuits. For a stereo TV, route the cables from both channels outside. Then close the device case. If you are not confident in your abilities, have this operation performed by a qualified specialist.
Choose a speaker system with an impedance that is similar to or greater than that of the TV's built-in speaker. Connect the cable you brought out to this speaker system. If one system has a lower impedance than your TV speaker, but you have two of them and their total impedance exceeds this, connect them in series. If your TV is stereo, connect a speaker system instead of each of the built-in speakers.
The second method does not require significant qualifications from the technician, but involves the use of an external amplifier and requires the TV to have a linear output sound. Remove the output signal from the Audio out RCA connector (body - common wire, central contact - output sound), from the DIN connector “Tape recorder” (the middle contact is common, and the output, depending on the year of manufacture of the TV, can be either the rightmost or leftmost contact) or from the SCART connector (pin 3 is output, 4 is common) .
Apply the signal to the input of the amplifier, where an RCA or DIN connector can be used. The connection method to these connectors is described above. The stereo amplifier has either two RCA connectors or one DIN, in which one of the outer contacts is used for the input of the right channel (which one depends on the year of its manufacture), and for the left - a contact located between the contacts of the right channel and the common wire. If the TV is mono and the amplifier is stereo, connect the inputs (but not the outputs!) of the amplifier together.
Turn on the TV and, if available, the amplifier. In the second case, first set the amplifier volume to minimum. Then adjust it to your desired level.
note
Do not carry out the manipulations described above with transformerless and autotransformer televisions.
To connect the TV to the system unit computer It is recommended to use a special cable. Most often, the whole difficulty lies in selecting suitable connectors.
You will need
- - video cable.
Instructions
Examine the video connectors present on the TV and video card computer. The latter device is usually equipped with VGA, DVI and HDMI ports. Older video adapter models have an S-Video connector. Modern SHARP TVs are equipped with SCART, HDMI, VGA and DVI ports (rare). Select similar or interchangeable ports.
Purchase a suitable video cable. Remember that there are special adapters that allow you to connect the following pairs of ports: VGA and SCART, VGA and DVI, HDMI and DVI. Naturally, when connecting the TV to a computer, it is wiser to use digital channels signal transmissions such as DVI and HDMI. Connect the video card computer and the corresponding TV connector.
Turn on both equipment. Go to the TV settings menu, go to the item responsible for assigning a video signal reception channel. Specify the port to which you connected the cable.
Now configure the video adapter settings computer. First, determine which display (TV or monitor) will be the main one. Remember that this is where applications and programs will initially run. Those. If you want to run games on the TV screen, then you need to assign this display as the main one. Open the video card settings menu.
Highlight graphic image selected device and activate the “Set this display as primary” option. Now specify the second screen operation option. For rational synchronous use of the TV and monitor, it is recommended to select the “Extend this screen” option.

Tip 4: How to connect your computer to your TV using a cable
To use the TV as a monitor for a computer, it is recommended to connect it via a special cable. The choice of its type depends on the availability of certain connectors in the computer’s video card and TV.
You will need
- - DVI-HDMI cable.
Instructions
First, find a suitable pair of connectors through which you will connect. Naturally, to ensure best quality images, it is recommended to use digital channels. Computer video cards are equipped with HDMI and DVI ports, which transmit a digital signal. Despite the fact that the DVI port is quite rare on modern plasma and LCD TVs, it can be replaced with an HDMI port using a special adapter.
Purchase a suitable video cable and adapter if needed. Connect your computer's video card to your TV. If you use a monitor and a TV at the same time, then the first device does not need to be disconnected. Now turn on both devices. Wait for the PC operating system to load.
Open the TV settings menu. Find the item that lists the connectors for connecting video cables. Assign the signal reception source to the port through which you connected to the computer.
Now set up your computer. Open your Control Panel and go to the Appearance and Personalization menu. Select "Connect to an external display" located in the "Display" menu. Now specify the display that will be the main one. To do this, select its graphic image and activate the “Make this screen the main” function.
Select the option for your monitor and TV to work in sync. It is recommended to use the “Expand screen” item. This will allow you to use your TV and monitor at the same time to perform different tasks. If you connected a TV to show a presentation, or you just want to use it instead of a monitor, then activate the “Duplicate screens” function. IN in this case Both displays will display identical images.

Sometimes the music center does not have an MP3 function, but the pocket player she is. But the player, unlike a music center, is not capable of sounding loudly. To correct this drawback, you need to connect the player and the center to each other.
Instructions
First, check your stereo for RCA input jacks on the front panel, labeled AUX or PHONO. Don't confuse them with headphone or microphone jacks - they are not only made to a different standard, but are also designed for a different purpose.
If you do not find such sockets, then carefully, so as not to tear off any cables, turn the music center with the back wall towards you. You will probably find such nests there. Do not confuse them with sockets for other purposes, which can also be made according to the RCA standard.
Now take the unnecessary headphones. Cut off the sound emitters from them. Purchase two RCA type plugs. Strip the wires that went to the sound emitter. One of the pairs consists of a clear (or yellow) and a red (or orange) wire, and the other has a blue or green wire instead of a red or orange wire. Connect all colorless or yellow wires to the ring contacts of the plugs, and the red (orange) and blue (green) wires to the pins.
Connect the cable to the player and music center. On the last one, select the mode called AUX or PHONO. If it has several inputs, they may be designated AUX1, AUX2 and the like. When searching for an input, set as to player, and at the center there is a small volume. In the future, set to player such a volume that the center preamplifier is not overloaded, and then adjust from the center side.
To prevent the player's battery from draining, connect the device to a special power supply that emulates a USB port. You can also use a powered USB hub that is connected to the unit but not to the computer. Remember that if the player is powered not by a battery, but by a battery, charging the latter in any way is not allowed. Using a music center together with a player does not exclude the possibility of switching it to other modes if necessary.
Tip 6: How to connect multiple TVs to one cable
There are several ways to connect multiple TVs to one cable. Their implementation depends on what type of signal reception you are using. On this moment The most common signals are satellite and cable.
You will need
- Sharp knife, pliers, adapters.
Instructions
To connect multiple TVs to cable TV, you will need to perform several steps. First, you need to purchase a splitter - this is a device whose task is to distribute a signal to several outputs. Reminiscent of a tee for sockets, only for coaxial cable.
Using tools, we connect the main cable to the tee, and then the cables from the TVs to the splitter. All inputs must be tightly clamped with pliers, since the quality of the signal depends on this. After the work has been done, we receive a signal on all TVs, and each of them can have different channels at the same time.
The second method is connecting televisions to satellite television. Everything here is much more complicated than in a cable signal. Mainly, you will need to determine how the receiver is connected to your TV. At the moment, there are different types connectors for connection. The most popular ports are VGA, DVI and HDMI. They are all different and you won’t be able to connect a VGA cable directly to the HDMI port.
You may need to buy adapters to connect, because the splitters you need only exist with VGA and DVI ports. It should be noted that the use of adapters significantly reduces the quality of picture and sound transmission.
To carry out this operation, you will need the same knife and pliers from the tools. Also, if you connect two or more TVs to the same satellite TV cable, all TVs will show the same channel.

The HDMI interface provides for the transmission of not only images, but also sound. If both the signal source and the TV support the Sound over HDMI protocol, there will be no problems. But what to do at lack of support for this standard in at least one of the paired devices?
Instructions
Submit sound signal You can transfer from the source to the TV not only via the HDMI cable itself, but also via a separate analog cord. Find on TV RCA connector labeled Audio in. If there are several, use the one closest to the HDMI input. Connect it with a cable to the signal source connector labeled Audio out.
Some signal sources do not have RCA connectors, but are equipped with SCART connectors. To remove the audio signal from such a device, use a SCART-RCA adapter. If you do not have such an adapter, use a SCART plug with the following contacts: 3 - audio output, 4 - common.
There are TVs that are unable to receive image data from one connector and an audio signal from another. In addition, not only televisions are equipped with an HDMI interface, but also large monitors that do not have amplifiers and speakers. In this case, your existing component audio system or music center will come to the rescue. Find on back wall amplifier free AUX jack (also RCA type) and feed the signal to it. If the source is stereo, connect it like this: the white connector is the left channel, the red connector is the right channel.
If there is no audio system, computer speakers will come to the rescue. On the signal source, find the headphone jack (do not confuse it with the microphone jack found on a DVD player with karaoke function) and connect the speakers to it. If the source does not have a headphone jack, feed the signal from its linear output to the preamplifier, and from the latter to the computer speakers. You can get by with a simple adapter that does not have a preamplifier, but the sound will be noticeably quieter.
If you have experience repairing televisions and are familiar with safety regulations, apply the audio signal directly to the amplifier of the device. Connect the common wires of the TV and the signal source together. Find the circuit diagram for the microcircuit on which the amplifier is built. Apply the signal to the input pin of this microcircuit through a capacitor with a capacity of about 0.5 μF.
note
Perform all switching operations with the equipment completely de-energized.
The method of connecting speakers to a personal computer depends both on the brand and model of the speaker system itself, and on external parameters system unit or a laptop to which the speakers are connected.
Active and passive speakers
All acoustic systems can be divided into two main groups: active and passive. Each of the groups implies its own option for connecting to a computer. Active speakers have their own amplifier and direct speaker system. As you know, the output signal of a computer has a voltage measured in units of volts, so such a signal must be amplified by an external amplifier. Such an external amplifier is contained in active speaker systems. Passive speakers consist only of the speakers themselves. In this case, you need to purchase an acoustic signal amplifier separately. Thus, it is the active speaker system that is most suitable for connecting to a personal computer.
Types of connectors
Depending on what kind of speaker system is used, different options for using the connectors are possible. The most suitable connectors in this situation are miniJACK connectors. If your speaker system has only two speakers, then it has one single miniJACK output plug. Such speakers can be connected to both the system unit and a laptop. If the number of speakers in your system is six, including a subwoofer, then the output of such a system should have three plugs for connecting each channel. Such a speaker system cannot be connected to a laptop and to some types of system units that have only two audio input connectors, without a special external sound card. Most personal computers has all three miniJACK input ports for connecting a 5.1 system. It often turns out that a sound system consisting of two speakers has two “Bell” type plugs at the output. This connector is not suitable for connecting to a computer. In such a situation, you need to purchase an adapter from this connector to a stereo miniJACK connector.
Connection procedure
So, if you have a 2.1 sound system, the output connector of which is a standard miniJACK, then insert this plug into the corresponding connector on the system unit or laptop, indicated by the image of headphones. If your speaker system has a three-element input, then you need to connect it based on the color of each of the connectors. The orange plug must be inserted into the pink port of the system unit, labeled with the image of a microphone. Insert the black plug into the socket located in the middle. Connect the green connector to the remaining space.
Modern computers in most cases come pre-installed operating system, with working sound. However, when reinstalling Windows or after an inexperienced user intervenes in the system, problems with sound playback may occur.
If the sound still does not appear, open the “Control Panel”, go to “System and Security” and then to “System”, select “Device Manager” in the left menu. In the list that opens, expand the “Audio inputs and audio outputs” item. If the driver is installed correctly on your system, you will see installed audio devices in the drop-down list. If you could not find this item, expand “Other devices”. Perhaps one of the unidentified devices will be your sound card.
Install the audio driver. There are several ways to do this. You can use the built-in driver search, but very often it cannot help. If the system was unable to install the sound card on its own, you will need to download and install the driver from the Internet. Type in a search engine a query with the name of your computer and the required driver. It is best to download it from the official website of the computer manufacturer. After downloading, install the driver in a standard way and restart your computer. The sound should work.
Sometimes when you connect a laptop to a TV via an HDMI cable, there is no sound on the TV, but there is sound on the computer. In most cases, this problem can be solved quite easily and quickly. Below we will describe several causes of the problem and methods for eliminating them for the Windows operating system.
It is worth noting that in some cases all the methods for eliminating the problem may not be useful, since the volume level in the operating system or on the TV is simply at zero. In addition, the Mute button may be accidentally pressed. All this needs to be checked so as not to do unnecessary work.
Setting up Windows playback hardware
As a rule, when connecting a laptop with latest version Windows to the TV via an HDMI cable, the sound starts playing immediately. But sometimes exceptions happen when the playback equipment remains the same and is not changed to new ones. In this situation, it is worth seeing if it is possible to independently specify the playback equipment.
You need to right-click on the speaker icon in the system tray and select the “Playback devices” item. Here you need to see what the default equipment is indicated. If NVIDIA is listed High Definition Audio, AMD (ATI) High Definition Audio, as well as some equipment labeled HDMI, then you should right-click and select “Use as default”. After this, you need to save your settings.
Most likely this will be enough to solve the problem. But it may happen that there is nothing suitable in the list of playback equipment, even if you set the display of hidden elements. In this case, it is worth using other methods to solve the problem.
Installing drivers for HDMI
It may happen that the PC does not have drivers for outputting audio via HTML, however, the video card has the “firewood” for this. This can happen during driver installation, when the user manually selects which drivers are needed and which are not.
To check this reason, you need to go to the device manager of the operating system. At any Windows versions to do this you need to press the Win+R combination and then type devmgmt.msc. After that, in the window that appears, you need to select “Sound, game and video devices.”
Here you need to check for hidden elements. This can be done through the “View” menu. Here it is worth paying attention to the number of audio devices. If only the sound card is displayed, then we can assume that HDMI audio drivers are not installed. It may also be that the HDMI device is installed but disabled. In this situation, you need to make a RMB on this device and select “Engage”.
If only the sound card is listed, then several steps are required. Initially, you need to download drivers for the graphics adapter from the manufacturer’s official resource. After this they need to be installed. If applicable manual setting installation, then you should pay attention to the HDMI audio driver. It must be checked and installed. For example, for graphics adapters NVIDIA calls this device "HD Audio Driver". After this you need to restart your computer.
It is worth noting that it may happen that the drivers do not want to be installed. The reason for this may be a failure of one of the current drivers. In this situation, you should try to uninstall all drivers and install them again.
If the sound from the laptop via HDMI is not played on the TV
If the methods described above did not help, and everything is correct in the equipment settings, then you should check the TV settings. It is also worth checking the cable itself, and if possible, testing another one. You can try connecting the old cable to another computer.
Sometimes a special HDMI adapter or adapter may be used to connect via HDMI, and the sound may also not work. When using an adapter from VGA or DVI to HDMI, the sound will not be reproduced accurately. If an adapter from DisplayPort to HDMI is used, then everything can function, however, some adapters do not transmit sound.
Additional data
In addition, drivers may be supplied with software, which may have its own HDMI audio output options for existing displays. You can also go to the NVIDIA Control Panel settings AMD Catalyst or Intel HD Graphics. But this helps quite rarely.
In principle, all of the methods described above can help solve the problem of no sound on the TV when connecting a laptop via an HDMI cable. If none of the above helped, then you can look for answers on forums where other users have already encountered this problem.
Sometimes when watching movies on TV, the sound from your 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.

Instructions
Most modern TVs, 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 the computer to the TV. If the TV supports stereo sound, then you will need two such connectors (red and white connectors on the TV), if mono, then only one (white connector).
On a computer, the audio output can be located either on the motherboard or on a separate sound card, if it is 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 the external contact of the “tulips”. One signal wire is soldered to the central contacts of both “tulips”. Assemble the connectors and connect the cable to the corresponding connectors on the TV and computer. Now the sound from the computer will be transmitted through the TV speakers.
