Sorry for the crappy screenshot (taken from Google Image)
Basically, I have my speaker setup (Analog Out) but if you look closely, you have an option for
Audio Channels. It's the first option from the top. The option I have are 2,4,6,8 Channels.
So yeah, I already setup my Analog Out as 5.1 Speakers... I just need to know which Audio Channel I should put them...
EDIT: Better Image (
Not my system though)
