No audio intel 82801JI - have /proc/asound/card0 but alsautils can't find hardware

[adante]

Hello. I somewhat foolishly decided to upgrade to 9.10 yesterday in the hopes that after 2 months in the wild it should be reasonably error free.

Anyway. It was - mostly. I can't boot I have to boot off've a 2.6.28-17-generic kernel because the 2.6.31-16-generic immediatelly throws some random kernel panic not syncing out of memory error*. I figured I could live with this.

Unfortunately I can't because it turns out audio doesn't work. Also unfortunately I no longer am in the position where I have the requisite 20 hours spare to fix this so I thought I would just post the basic information here in the hopes that someone might know of a quick fix.

attempting to run various alsa tools shows there are no devices :

adante@veer:~$ aplay -l
aplay: device_list:223: no soundcards found...
adante@veer:~$ alsamixer

alsamixer: function snd_ctl_open failed for default: No such file or directory

yet strangely there seem to be alsa devices in /proc/asound/:

adante@veer:~$ cat /proc/asound/cards

A friend suggested I install linux-backports-modules-2.6.28-17-generic so I did. After a reboot it was much the same.

I would appreciate it if someone could advise me as to the most painless manner in which I can get audio working again. If one such exists.


* incidentally I was going to report this but you can't do this on the web anymore, and 'ubuntu-bug linux' claims this is not a genuinge ubuntu package, and 'ubuntu-bug linux-image-2.6.31-16-generic' wants to upload a 350 meg bug report.
