# No sound after Liquorix Kernel update

I recently installed the Liquorix Kernel after hearing that it had the 200 line patch in the kernel.

Once I installed it, everything worked great and I had HUGE performance improvements. At that point i was using the 2.6.36-14 version.

The kernel has now updated twice to version 2.6.36.-16 and now I have no sound coming from my system. Alsa mixer shows that nothing is muted.

How can i resolve this issue?

Here is the script output file everyone requested. alsa-info.txt

You may need to contact Liquorix Kernel maintainer to get help. I have only one clue: you need to rebuild the sound stack (alsa and pulseaudio) to get it working with Liquorix. Thanks! –  crncosta Nov 23 '10 at 20:52
PulseAudio shouldn't need to be rebuilt if the change was only effected by a kernel update. –  Daniel T Chen Nov 23 '10 at 21:07
Yes it is only affected by the kernel because booting into the official ubuntu kernel, the sound works fine. –  user6465 Nov 23 '10 at 21:28
Have you executed the recommended script as referenced at askubuntu.com/questions/14596/…? –  Daniel T Chen Nov 24 '10 at 11:50
Yes, I executed the script and its posted below. –  user6465 Nov 25 '10 at 0:38

I would argue you should ask in the Liquorix forums. Only a few people here have experience with the patches it uses.

Something to try before you do though, and it'll sound silly, but have you run alsamixer and checked that it isn't muted? Sounds silly, but you wouldn't be the first person to overlook it. We've all done it at least once ;)

I check and no, my sound is not muted. Thanks for the tip though. –  user6465 Nov 24 '10 at 5:47

Please see Ubuntu sound not working, thanks!

If you feel odd about posting a bug report in Launchpad, the procedure we normally follow to request necessary information is to ask that a developer's debugging shell script be executed. This bash script is available at http://www.alsa-project.org/alsa-info.sh, and you would execute it using bash ~/Desktop/alsa-info.sh --no-upload in a Terminal provided you saved the shell script to your Desktop. You can then pastebin /tmp/alsa-info.txt and/or link to it from a response here.

I wouldn't recommend filing a bug for something that only happens when a 3rd party kernel is installed. –  8128 Nov 23 '10 at 20:45
Normally I wouldn't either, but asking someone to endure a rather laborious information-gathering process is worse than having a bug filed then converting it to a question - or just having it filed as a question directly. The former approach is preferable, because we gather all the necessary information using apport hooks. –  Daniel T Chen Nov 23 '10 at 20:51
