There was a partial workaround to get sound working again here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/288861
where alsamixer -Dhw revealed that the PCM volume was at zero, and turning it up restored sound operation. I still have the problem that my system hangs during shutdown while it is shutting down ALSA.
