i recently purchases the xtreme sound 7.1 card and im trying to hook up my dad's old sony reciever....exactly what kind of cables do i need? the card as s/pdif in and outputs and i tried just hooking up using RCA cables from the output of my card to the input of the receiver but obviously there is only one jack for the card and a set of red and white for the receiver and when a speaker is hooked up and the card switched to s/pdif all i get is static....do i need a special cable? heres a link to what my card is http://shopping.yahoo.com/piamond%20Multimedia%20Diamond%20Xtreme%20Sound%20X S71%20Sound%20Card:1993239001;_ylc=X3oDMTB0OXA5YnR 2BF9TAzk2NjMyOTA3BHNlYwNmZWVkBHNsawNjb21w
