Dell Latitude 6500: No audio in 2.6.28-11

[AndyT]

I just installed 9.04 on my Dell Latitude 6500 and got no audio at all. When booting the 2.6.28-11 kernel, all the hardware appears to be present and working but still there is no audible output on either the speakers or the headphone connectors. Booting 2.6.27-11 makes everythign work fine. For comparison, I ran alsa-info.sh on both kernel versions; see http://www.alsa-project.org/db/?f=3df721082da7c7eda1da7ea636c30630ca4efbfe for the 2.6.27-11 and http://www.alsa-project.org/db/?f=ca18f3045fff601634ad07e81a39887fbec076bf for the 2.6.28-11

I have the exact same problem on a E6400 : sound worked in 8.10, broke after a 9.04 update, but works again when using the 2.6.28-11 kernel.

There seems to have been sound issues with E6x00 reported for 2.6.29 (http://lkml.org/lkml/2009/4/15/249), could this be linked ?

I have exactly the same problem.
Cfg:

- Dell E6500
- Ubuntu 9.04

Everything was fine until Ubuntu 8.10 but sound support in 9.04 has been somehow broken.

Hi AndyThaller,

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 363739

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.
