OK, I've had this card for about 4 months and I've been using it with my receiver without any issues...... Then I move.... I'm in the process of trying to arrange my PC, and really don't have the room for a receiver, so I decide to run this through my Compass (been locked up for 4 months, and it's been babied throughout my ownership). I use the optical out to the SPDIF on the compass... and nothing.... I then try the optical to optical... nothing..... I then run right and left outputs to the corresponding "Line In"... still nothing (Tried all three settings USB, Coax, and Optical)... Using latest PAX drivers as well.... Insert AGH!!!!! I really need some help in figuring this out..... I'm going to try and use USB to see if that works.. but this is not quite what all I had imagined. Any and all help is more than welcome & sincerely appreciated.... OK.. tried USB. Windows7 recognizes Compass, but still no sound out.. Is my DAC/Amp toasted???
