How to transfer sound from computer to TV
You will need
  • Soldering iron, one or two connector RCA (Tulip), one TRS connector 3.5 mm (mini-Jack), two-wire shielded cable, the knife.
Instruction
1
Most modern TVs in addition to HDMI, S-Video and SCART, I have the RCA connectors, which in the vernacular is called "tulips". It is through them we will transmit sound from the computer to the TV. If your TV supports stereo sound, then these connectors will need two (red and white connectors on the TV), if mono, then only one (the white connector).
2
The computer audio output may be on the motherboard or separate sound card if it is installed. Typically the nest has a light green color. If the sound from the motherboard you have divorced on the front panel of the chassis, this slot is at the front, otherwise the back. Connected to TRS connector 3.5 mm, which is commonly called the "mini Jack".
3
Take the cable of the necessary length with a knife and clean it from both sides. Proceed carefully, take care not to damage the wire when the insulation is cut. The shield gather to one side and twist into a pigtail. For what would a brazing process developed better leads must be tinned with stinging. Disassemble mini-Jack and solder the shield to the large lobe, and two wires to the two small petals. Now assemble the connector back.
4
It is time to engage the other end of the cable. If you need a mono signal, then solder to the exterior of the "Tulip" screen, and the center contact both signal wires. Before you solder the connector to the wire, don't forget to put on it Unscrew the part of the connector. If you have a stereo sound, then the screen should be divided into two parts and solder each part to external contact "tulips". To the Central contacts of both "tulips" is soldered on one signal wire. Build the connectors and connect the cable to the respective connectors on the TV and the computer. Now the sound from the computer will be heard through the television speakers.

Advice 3 : How to enable sound on TV with HDMI

The HDMI interface is to transfer not only image but also sound. If the Protocol is Sound over HDMI support signal source and the TV, no problem. But what to do with the lack of standard support at least one of the matched devices?
How to enable sound on TV with HDMI
Instruction
1
Sound source on the TV can not only to HDMI cable, but a separate analog cable. Locate your TV RCA Jack labeled Audio in. If more than one, use the one closest to the HDMI input. Connect it with a cable connector of the source signal labeled Audio out.
2
Some sources do not have RCA connectors, but connectors are equipped with a standard SCART. To remove such a device beep, use the SCART adapter to RCA. In the absence of such adapter use SCART, which use the following contacts: 3 - audio output 4 - shared.
3
There are TVs, deprived of the possibility to receive data about the image with one connector, and the audio signal from the other. In addition, the HDMI interface equipped with not only televisions, but also large screens and amplifiers and speakers are absent. In this case, come to the aid of your existing component system or music centre. Look on the back of the amp loose connector AUX (also RCA) and send the signal to it. If the source is stereo, connect: white plug left channel red - right.

In the absence of the audio system come to the aid of computer speakers. The signal source find the headphone Jack (don't confuse it with the microphone, your existing DVD player with karaoke function) and connect speakers to it. If the earphone Jack on the source of no, the signal from its output line feed to the preamp and from the last - in computer speakers. You can do a simple adaptor, in which the preamp is missing, but the sound will be noticeably quieter.
