OK I have hooked up an old soundcard that was in the pc so I am going digital coax from pc to 861 and USB isn't involved at all. Same issue. And as I said before this new connection is to a different card than the USB connection. I am trying to contact my dealer and see if I can get the firmware to try and reinstall that. I played a CD through my Bluray player that goes through the HD621 and same issue. Something to do with stereo?
