No sound at all

[John Berkhout]

Noticed today that getting new mail did not result in playing a sound. Did a check, but it seems that sound is completely dead.
Did try to install the newest alsa drivers. Added the PPA, did the update.Installation failed. Sytem reported that there was no package for 'linux-alsa-driver-modules-3.2.0-25-generic-pae'

Version 11.10 (on an other partition): sound works ok.
So probably a system update during the last couple of days broke it.

[John Berkhout (jfberkhout)]

Followed the two sound troubleshooting guides on http://ubuntuforums.org/showthread.php?t=1885240 without results.
Alsamixer settings are identical between 11.10 and 12.04.

Other actions:
- booted from live CD 12.04 -> sound ok
- did a fresh install of 12.04 -> no sound

does someone has a clue?

Problem solved by http://askubuntu.com/questions/153602/ubuntu-12-04-sound-only-comes-in-headphones-doesnt-come-in-inbuilt-speakers-h

"This seems to be a recent issue as I have this problem also in my HP Pavilion dv61355dx. The following is only a temporary fix to put sound on the in-built speakers but will not send audio to the headphones (at least in my case).

sudo gedit /etc/modprobe.d/alsa-base.conf

Make sure to back up the document before modifyng it and add the next line at the bottom of the document:

 options snd-hda-intel model=dell-m4-3 enable_msi=1"

This indeed solved the issue.
