well the other cords are for the sp/dif out on the card.
try messing around with the options in the creative surround mixer, there is an option in there to have it as 2.1, 4.1 or 5.1 or headphones, and it has all the EAX options in there as well as bass and treble and all that. If anything, that would be your problem, I don't think this is a driver issue. Hit me up on MSN - email@example.com
