I recently built a new pc. I use the optical output for sound to a receiver for 5.1 sound. I'm using XP Pro x64 which could be the problem but the sound only comes out of the left and right speakers and I tested the speakers in my old pc using the same connection and it works so it is this computer. I have a MSI K8N SLI-F mobo:

and the onboard sound is RealTek. My receiver shows whats speakers are being used and while plugged in it only shows the left, right, and sub( hasn't worked on this system either ). I've updated bios, got all the latest drivers to my knowledge, if anyone can help that be great thanks in advance.
