I have a new Dell 4th gen XPS gaming system. Inside of this beast is a Soundblaster Audigy 2 ZS. My question is, how do I go about hooking up my home theatre surround sound to this card? Would I be able to utilize the digital output and actually have surround sound coming out of my computer? What kind of cable would I need? Or do I just get a stereo mini to RCA cable and plug that in? (That would only get me stereo, I know.) Actually having 5.1 sound would (obviously) be the best, but I'm curious if it can be done using my home theatre system. Any input would be greatly appreciated.
