You'll need to use the S/PDIF pinouts on your motherboard and construct
either a coax or optical bracket, then connect this to your amp via it's
own coax or optical input. Then you just use the AC-3/DTS passthrough
option.
Some motherboards already include coax or optical socket (for example,
my ABIT AN-M2HD has an optical connection) which makes things a bit
easier for you (assuming your amp has the same connection!)
You do lose a couple of features (for example, you can't control the
volume on a pass'ed through signal [nor would you want to]).
