I too seem to be affected by this bug. Ubuntu 10.04 LTS updated as of last week:
pulseaudio 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14
gnome-media 2.30.0-0ubuntu1
libasound2 1.0.22-0ubuntu6
I have both an SBLive! card and built-in audio in this system - the inability to adjust left/right balance (and associated lowering of main volume) via g-v-c applies to both of them.
