Dave, thanks for the pointer. Installing alsa-hda-dkms package from the above repository fixed the problem. I now have full card functionality in alsamixer, and things seem to be working properly.
When can these upstream changes be expected to make their way into the main distribution?

For the sake of others reading this, what I did was: sources. list.d/ ppa.launchpad. net/ubuntu- audio-dev/ alsa-daily/ ubuntu precise main ppa.launchpad. net/ubuntu- audio-dev/ alsa-daily/ ubuntu precise main d/alsa- base.conf
1. Added the following file to /etc/apt/
deb http://
deb-src http://
2. Ran apt-get update; apt-get install alsa-hda-dkms
3. Removed the line "snd-hda-intel model=generic" from /etc/modprobe.
4. Rebooted.
