Thanks very much for the replies guys.
So your saying, games I'm playing now like COD4, Bioshock, Team Fortress 2, and Battlefield 2142 don't support any type of surround sound gaming?
I thought for sure I'd just pull out my optical cable, connect to receiver, check the settings in the sound card software, and voilla all games would output surround sound.
One interesting thing to note, when I setup the optical output in my sound card software, it had a sound test that would hit all 6 speakers. It only worked on L and R channels for some reason though.
But irrespective of the above... your saying games don't output 6 channels? Do any games do it or none at all?
