If your media files compress+encode the audio in AC3/DTS (up to 5.1 channels) already, it is possible to configure media player software to bitstream that audio directly to the receiver and the receiver handle it. Of course Windows default won't do it for you. You need apps like AC3filter and MPC-HC.

How do the ATI video cards pass the uncompressed sound to the receiver? Via HDMI? My receiver doesn't have HDMI inputs.
