I have what may be the same problem, and have also noticed that the "Analog Stereo Output" profile is missing from the list of profiles in pavucontrol in Karmic (only 4.1, 5.0, and 5.1 profiles area available for output); the USB sound device worked just fine for me in Jaunty too, and I'm fairly certain the normal stereo profile was in use at the time. Could this be related?
