I posted this in Technical support too, but I figured it would be good to post it here too.

I have a Abit KN8 SLI and i have 8.1 surround sound onboard. I want to use the surround sound, but cant get it working.

all i really need are the Left, Right, Center, and Sub channels to work because I only have a 4 channel amp.

My system specs:
Abit KN8 SLI
AMD Athlon 64 3500+
1.5gb DDR400
160gb WD HDD
2x Gigabyte GeForce 7300 GT's
