Public bug reported:
Ok, it all worked fine when I first installed Ubuntu12.04. Indeed it
works if I use the USB installer and boot from it. Dies a horrible
death if I try to use the alsa-hda-dkms stuff. Actually removes all
audio devices completely.
I needed to do this to get back the card after trying the alsa_hda_dkms
sudo apt-get purge alsa-hds-kms
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get
update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base
alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r`
libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-
base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2;
killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group |
grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e
'^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`
Ok, so response to aplay -l is
**** List of PLAYBACK Hardware Devices ****

grep "Codec:" /proc/asound/card*/codec*
/proc/asound/card0/codec#0:Codec: Realtek ALC272X

But sound settings on desktop finds now hardware.
Please note, it lost audio all by itself.
