I'm trying to get some LEDs to be synced with sound. I'm trying to find the pins for the left and right audio on a fat PS2 motherboard. All I can seem to find is a pin with a solid 10v and 2 pins that seem to be synced with the brightness of the TV. All the others aren't reading any voltage.

  • Can you confirm that audio is actually being output through this connector? The reason I ask is that I found on my PS3 I needed to change a setting for that to happen. Commented Mar 23, 2017 at 9:52
  • @Wilson I'm not sure of the specific details, but I do recall that AV is output through the HDMI cable or the origins AV port, but not both at the same time. When I finally got an HDTV, I had to change the output settings on the PS3. Is that what you are referring to?

  • The ps3 has multi out so you can use both outputs. Its how I use my surround sound.

1 Answer 1


I found two neat pictures that show the pin order on the AV out port and the AV cable.

PS2 AV Cable

PS1 AV Out

From the left in the bottom picture, pin 2 is the right audio channel and pin 4 is the left channel.


  • Do you think the pins line up on the motherboard like that?

  • Ayy, thay do. Unfortunately they don't push out enough voltage to do what I want. Thanks for the help JAL.

  • @Justin If you need more power, pin 10 is a 5 volt line.

  • But wouldn't that corrupt the audio?

  • @Justin Hmm, not sure. Either way, probably not a good idea to touch that in hindsight.
