Okay still in trouble. I have my old 2.1 connected on my line1 out. I have the coax connected on SPDIF (it's a STEREO mini jack on the sound card). I've set the receiver to accept audio from the appropriate source. I've set the AudioHQ > Device Controls > Decoder to SPIDF and sampling rate to 48 Khz.
Additionally, under the THX control panel i have Digital Output only checked and Speaker/Headphone selection to 2/2.1 Speakers (not sure if that matters).
However when I play an mp3 test song on iTunes, I hear nothing on the speakers through my receiver. However, I do hear sound from my old 2.1
What gives?? What do I need to do to get the soundcard to output to my reciever??
