Runing two Audio Cards in MCE

just wondering if this is possible. i'm trying to run two audio cards at once, x-mystique for dolby digital live to my reciever, and audigy 2 card to run analog sould to a pair of powerd desktop speakers in another room. They are both installed and suposedly runing correctly, but i can't get analog sound out of the audigy. Hints? tell me to give up? Couldn't find much info anywhere.

thanks
