Dell E6400 No sound in Ubuntu Karmic

[guncharly]

I upgraded from Jaunty to Karmic and now I have no sound (in or out).

I tried to reinstall several audio packages, play with alsamixer and pulseaudio settings but nothing improved.

Sound is working well on windows so not a harware faillure.

I ran alsa-info.sh and the ouput is at :

Thanks for your help.

Please remove the model=auto quirk that you're using; install
linux-backports-modules-alsa-karmic-generic; and reboot.

Thanks Daniel.

Everything works now.

Hi guncharly,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 477526

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I can confirm that I have no sound in Ubuntu 10.04 and on a Dell E4310. I had sound in the beginning, but I believe sound disapeared when I changed kernel.
Output of uname -a: 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux

I have to run kernel 32-22 because of heavy screen flickering when running 2.6.35.21
