I have a Radeon 7970 and I'm using it with a Onkyo hdmi reciever. I'm running Windows 8. If you do an audio test of rear left and right 5.1 channels, the audio is always reversed from what it should be. This of course isn't a speaker problem, the pc is the only device that does this. I've searched for a way just to switch the channels and can't find one. I'm running the latest amd beta drivers. I've had to resort to just changing the audio setting to stereo because I can't find not way to reverse the surrounds. Any ideas?
