i just spent money on a cambrige soundworks surround system ... now i have it hooked up to my sblive platinum 5.1. I am using the digial out on the back of the sblive card and i checked that box in the play control labled "Digital out only". and in Surround Mixer turned on "AC-3 decode". and have my speakers set to 5.1 speakers. but still when i do the "test" in Surround Mixer it just does front left and front right out of my center speaker.... and my receiver says that it is only a 2 channel singal... how do i get it into the 5.1???
 
 
the receiver is a marantz 7000
with model seventeen bookshelf
and a Center Channel II
using the $1.50 monster cable
(the cable of the computer is going to the digital in on the reciever)
