[HDA-Intel - HD-Audio Generic, playback] No sound at all after Ubuntu 12.10 update

[Kuba Iwanicki]

No sound at all after Ubuntu 12.10 update (beta version). There was an error with alsa-hda-dkms so I uninstalled it. I tried to procede with this tutorial:
http://www.ubuntu-pomoc.org/aktualizacja-alsy-dzieki-jednej-komendzie/
but there is no results. Still there is no sound.

Can someone tell me what to do to get sound back?
