Dave,

After about 8 hours of fiddling with this, I found out what my problem
is. I had added to update manager software sources,
ppa.launchpad.net/ubuntu-audio-dev/alsa-daily/ubuntu . This puts
alsa-hda-dkms as a package to update in update manager. One of the
drivers in there was causing my problem(that is, in system settings for
sound, output was "dummy-output", and I could not perform a speaker
test). When I restored from backup, and took the ppa out, the rest of
the updates were successful, and I still had my sound. I'm now on the
latest kernel, 3.2.0-24 .

I guess this bug #989955 can be forwarded to the alsa-dev team.
Wouldn't want this to show up on some future update. On another
computer, I still have another sound bug #980070 that has a work-around,
I just unplug/plug back in the HDMI cable, athough this is rather
annoying, as Ubuntu 11.10 worked just fine.
Thanks
