Since upgrading to 13.04 I've lost sound. Had it on 12.10.

viktor@hedefalk-i7:~$  cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xfb520000 irq 89
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfb080000 irq 44

I've tried everything over here:

... lots more

Also tried reinstall with:

  sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2

Nothing helps :(

Didn't you read a not that the link is outdated? use this one and post results back wiki.ubuntu.com/DebuggingSoundProblems –  Stefano May 28 '13 at 13:04
    
That link doesn't say much at all. I opened a bug finally from the instructions over there. bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1206121 –  hedefalk Jul 29 '13 at 13:54
