Just built a computer for a friend last night (Asus P4S800) and we ordered it because he wanted 5.1 sound (6 channel soundmax) ... It has regular Line In, Line Out, and Microphone... and then a SPDIF port. I'm guessing that because there are not regular 5.1 channel outputs like on my Audigy, the SPDIF is the only output for 6 channel sound.... am I right? Is he going to have to buy 6 channel speakers with a SPDIF input? If he has a regular receiver with his TV and DVD player hooked up that has SPDIF does he use that? Heeeeeelllp =)
