View Full Version : [ubuntu] Kernel 2.6.24-23-generic killed my sound

I lost all multimedia playback when I did the latest recommended upgrade to the 18.104.22.168 kernel. I couldn't figure it out for a while, but when I went back to my previous kernel ( 2.6.24-22-generic #1 SMP Mon Nov 24 18:32:42 UTC 2008 i686 GNU/Linux ) all the sound came back.
I haven't seen much on the forums about this, but then I only looked in the multimedia section.

Killed my sound too. ...and my nvidia driver. Only for geeks at this point.

Can you guys tell me how to upgrade/downgrade my kernel? After I upgraded to Intrepid, I lost my sound card(s) (Nvidia and Aureal Vortex). I suspect my kernel: 2.6.25-2-386 isn't working with Alsa. Recompiling from latest Alsa doesn't make it through the Make step.

The system normally keeps your current kernel and the previous one.
What I did was install startupmanager ( apt-get install startupmanager) first. Once you get startupmanager installed just run it:
You will see a GUI that has a dropdown menu for "Default operating system" and you can just select the previous one. Then just do a normal restart.
In my case my 2.6.24-23 caused my loss of sound so I just told startupmanager to use 22.214.171.124 and "VOILA" my multimedia all returned.

You are probably just missing the required modules
dpkg -l |grep linux
and look for linux-ubuntu-modules and linux-restriced-modules you'll probably find that you have the ones for the old kernel and not the new kernel
