Here's an easy solution..... have a local radioshack nearby? have an old rca cable laying around? you're in luck! Run to ratshack, find the phone--- 1/8" plug for 4 bucks, stick it on one end of the rca cable, 1/8" go into Audigy 2 ZS, other into receiver's coax input..... voila!!!
I am also running this for my computer with an Audigy 2 ZS btw. works great.
