    Thanks, that does make sense and it was what I was hoping. Does the video card get the HD sound from the sound card or an embedded chip on the MB?

    If you have content with HD audio, you have two choices.

    1. Decode the audio using software codec (e.g. Blu-ray playback software deocdes). The audio is then sent in an uncompressed format (called LPCM) to the AVR via HDMI.

    2. “Bitstream” the HD Audio via HDMI. It is called bitstream because the compressed bitstream is sent to the AVR exactly as it was received. Bitstreaming requires something called a Protected Audio Path (PAP). Your AMD graphics card supports PAP, so this option is also available to you.
