Public bug reported: Since the kernel was updated and I installed linux-backports-modules- alsa-karmic-generic, I got ALSA 1.0.22.1
$ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.22.1. Compiled on Feb 8 2010 for kernel 2.6.31-20-generic (SMP). $ And now I don't have sound. If I use ALSA 1.0.20 or ALSA 1.0.21 it is OK. I get sound either by removing linux-backports-modules-alsa-karmic- generic or by choosing the previous kernel at boot (2.6.31-19).
