alsa sound does not work out of the box on a dell latitude xt 2

[Marc Nieper-Wißkirchen]

Binary package hint: alsa-base

I am running the current testing version of Ubuntu 9.10 on my Dell Latitude XT 2. The sound does not work out of the box. After I have added "options snd-hda-intel model=dell-m4-1" to "/etc/modprobe.d/alsa-base.conf" I can listen to sound from my computer.

I'd suggest to improve Karmic in this regard before it is being released by either

a) changing the alsa code so that the Latitude XT 2 works with the snd-hda-intel driver without any special options,
b) adding the model dell-m4-1 to the options whenever a Latitute XT 2 is detected.

Of course, b) could be improved by adding a new model option to the snd-hda-intel driver (IDT 92HD71B7X codec) for the Latitude XT 2.

Thanks for helping us trace down this bug! Can you please run "apport-collect 428555" so we can see what PCI ids Dell Latitude has?

Let apport upload the requested information.

P.S.: Not only model dell-m4-1 works, but also dell-m4-2 and dell-m4-3. Don't know which is the best to pick here.

Thanks so much for submitting this bug. I had been working on getting audio to work for days.

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 alsa-base 428555

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 have upgraded to Ubuntu 10.04 and the sound (including recording) seems to work without any changes to alsa-base.conf.

Thus (at least for the current development system) the bug may be closed.

Thanks a lot!
