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.
I found two neat pictures that show the pin order on the AV out port and the AV cable.
From the left in the bottom picture, pin 2 is the right audio channel and pin 4 is the left channel.
