Andres, can you confirm that installing linux-backports-modules-alsa-karmic on current Karmic resolves the issue for you? Please also use: apport-collect -p alsa-base 409819.
Other commenters: please refrain from commenting on this bug unless you have _identical_ hardware to Andres's. So, until he posts his hardware, you should _not_:
1) add "me too" comments;
2) add your apport-collect information to this bug.
You _should_, however, file a separate bug using ubuntu-bug alsa-base, change the affected source package to linux (instead of alsa-driver or pulseaudio), and add a linux-backports-modules-2.6.31 task.
