Computer to TV Speakers Hookup



How to listen to your computer on your TV Speakers


By connecting your computer to your TV you can listen to music on larger speakers and get plenty of volume using your TV sound amplifier.

Watch YouTube Videos on your computer PC or Laptop and listen to sound on your TV speakers

Your computer speaker or speakers may not be loud enough or good enough for the sound you want. For louder sound connect computer sound out to your TV and use the TV amplifier to listen on your TV speakers.

You may not have any larger speakers, that is OK. Why not use your TV speakers. You may not have a stereo system, that is OK. Why not use the amp in your TV. Turn up the volume on your TV and listen to louder, richer sound from your computer.



You need:

1) a TV
2) an audio cable to connect computer to TV,
3) a computer, PC or laptop

TV inputs



Your TV has inputs no matter how old or new it is, from the newer HDMI to the older RF coax input. If your TV has a yellow, white, red composite input or just a yellow and white or a yellow and black input, you can connect your computer to the TV by connecting a 3.5mm RCA audio cable from the computer's headphone jack or the green speaker out jack to the TV RCA audio input. You are only connecting the white RCA cable or the white and red for stereo.



This older TV only has mono audio input, the black audio input, so you would connect the white RCA cable to this black audio input. The red is not connected. Then select the correct VIDEO input on the TV. These older TVs only have one video input which is usually selected by a button labeled TV/VIDEO.



3.5mm male to RCA stereo audio cable


Plug stereo cable 3.5mm into computer output jack. This can be the headphone jack on a laptop or the green speaker output jack on a desktop computer.

Plug the other end of the cable into the TV RCA inputs. This can be a 3.5mm (Aux) or the two RCA (white and red) cable connectors.

Plug in and power ON.
Adjust volume
Select sound source and Play

Analog Wired Connection


Cable to connect PC or laptop to TV



Cable has 3.5mm stereo plug for sound card or earphone jack output connection and at the other end is two RCA plugs for left and right stereo channels.




  • Laptop or desktop computer with sound card or earphone speaker jack.
  • TV with available audio in jacks.
  • Stereo 1/8" mini jack-to-RCA plugs Y adapter cable. Available at local and online retailers.




Power ON TV and use TV speakers for sound from computer.

For newer TV with combo audio video 3.5mm input usually labeled AV IN, use adapter cable. Be sure to select correct video input on TV.

Simple RCA cable connection for earphone jack or soundcard hookup.

For an older TV with only RF antenna input or only twin lead input, use an RF Modulator to connect, switch TV to channel 3 or 4. Use a 75 ohm to 300 ohm BALUN for older TV with only twin lead terminals to convert coax cable to twin lead.

PC to VCR to TV

Another option if you have a VCR but do not have an RF Modulator is to connect through a VCR to the older TV. This is because the VCR has a built-in RF Modulator.

Connect the 3.5mm audio plug to the computer audio output and connect the RCA end of the same cable to the VCR audio INPUTs.

The RF coax TV input is only mono audio so you only need the white RCA audio plugged in to VCR. The VCR then has a RG-6 coax cable from the VCR RF output to the TV RF antenna (VHF/UHF) input.

Switch the TV to channel 3 or 4.
Switch the VCR to LINE input. Some VCRs have a rear and a front LINE input so switch the VCR to LINE1 or LINE2. LINE2 is usually the front and LINE1 is the rear audio inputs. Switch the VCR to VIDEO, not TV. Power ON VCR.

Play source on computer. Audio goes from computer to VCR and out to TV. Turn up volume on TV.





Most PCs today have a soundcard already installed when you buy it. If not, you can purchase a sound card and install it yourself. The sound card has ports for connecting speakers, mics, etc. The green port is for sound going OUT while the blue port is for sound coming into the computer. The pink port is for a microphone. Most PC soundcards utilize a 3.5mm (1/8-in) jack as the line input or output connector.

Sound Card



The Sound card in a personal computer typically has three round jacks color coded and indicated with symbols for line out, line in and microphone in. The jack of interest is the line out usually color coded green or having text label OUT possibly with a symbol showing an arrow going out from concentric circles.



Launch your music player on the computer, select music and play. Adjust the volume. The sound will now be coming from your TV speakers.
