[Bug 535622] [NEW] no sound after update to 2.6.31-20

Binary package hint: linux-backports-modules-alsa-karmic-generic

Hello,

I think that there is a serious issue with alsa drivers in 2.6.31-20.

After upgrading from 2.6.31-19 to 2.6.31-19 I have no more sound, and
the alsamixer and gnome mixer don't show any playback devices, actually
they don't show any device at all !

I rebooted on the 2.6.31-19 and can confirm that everything seems to
work pretty good with that version : sound is ok, mixers as well.

Here is the result of the alsa-config after the upgrade to 2.6.31-20

And here is the result on the working 2.6.31-19 :

I'm willing to issue any comands/operations if you need aditional
information.

Regards,
