This looks like a duplicate bug report to https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/352732
The advice I've been given is
sudo cp /etc/init.d/alsa-utils /etc/init.d/alsa-utils_old; gksudo gedit /etc/init.d/alsa-utils
scroll to line 378 which reads: mute_and_zero_levels "$TARGET_CARD" || EXITSTATUS=1
and comment it out and reboot
I've not tried it yet, thats a job for tonight
