Note, I never see any indication of HDMI with aplay -L, only with aplay -l
At that point, I can get sound by the Pref-Sound panel, switching everything to nVidia HDMI.
Also note that you appear to need 177.80 to get any sound, and 177.82 if you want 5.1. I have personally rolled back to 173 b/c 177 kills Flash performance on the 8200, but 173 does not appear to support audio over HDMI (aplay -l shows the device, but no sound...), so I am using 173 HDMI video and the 6-ch analog outputs until I hear back from nVidia.
