Before my rebuild last night I was using the Realtek ATI HDMI driver, but after doing some research on avsforum.com it sounds like a lot of people are getting away from that now. So I didn't install it this time around.Personally I wouldn't I had no success at any time with it, the default one just works - for me obviously. For reference though there is only an ATI HDMI, or Realtek Driver, but no Realtek ATI HDMI Driver.
When I get home I'm going to do a quick backup and install the Realtek ATI HDMI driver to see if it makes a difference.
Purely out of curiosity, perhaps you should double check your Windows sound set-up - the only time I get 2 channel sound from my ATI HD5450, was and is when I forget to configure Windows sounds to 5.1 (I know you said that had been done in an earlier post, but might be worth re-checking):-
Control Panel/Sounds/Playback and Highlight ATI HDMI output, then press configuration button in the bottom left hand corner and follow the steps to configure to 5.1 set-up (or 7.1 if that is what you have) - the default value is 2 channel stereo.
