- Install Ubuntu Intrepid (my friend had already done this)
- Update alsa-libs to most recent stable version. This was higher than the
- Edit /etc/modprobe.d/alsa-base to include the specific codec type.
- Make certain the volume was ALL the way up.
Alsa libs update was accomplished via soundcheck's script posted here on ubuntu forums. This compiled the newest alsa-libs, 1.0.18 in my case.
Further down in the post Temujin reposted model-specific information for the codec returned by the following command:
cat /proc/asound/card0/codec#* | grep Codec
In my case it returned:
Codec: IDT 92HD71B7X
Codec: LSI ID 1040
Neither matched Temujin's list, but googling for 92HD71B7X led me to oldcpu's post on forums.opensuse.org. oldcpu pointed out that this was similar to STAC92HD71B* from Temujin's post. I added the line:
options snd-hda-intel model=dell-m4-1
to the file
The model doesn't make sense (this is an HP computer) but the sound worked after reboot. Huzzah!
