[Dell XPS 13 (L321X)] Regression: audio stopped working after upgrade to 13.10

[Dima Ryazanov]

After the upgrade, sound stopped working for me. The volume would always be set to 100% after booting, though I couldn't hear anything.

WORKAROUND: I went to the audio settings, and discovered that the hardware profile was set to "Digital Stereo (HDMI) Output". Changing it to "Analog Stereo Output" fixed the problem.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1244501

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Dima Ryazanov (dima-gmail)]

Yes, the bug also exists in upstream kernel - though I don't know if it's actually a kernel bug. (I just didn't know which package to pick.)

It looks like something caused the audio settings to change during the upgrade.

[penalvch (penalvch)]

Dima Ryazanov, could you please boot into a live environment of Raring and execute the following in a terminal:
apport-collect 1244501

[Dima Ryazanov (dima-gmail)]

It actually keeps happening: the output device gets changed to HDMI on its own once in a while. I don't have a Raring environment right now; I'll try to figure something out, though.

Also, I don't think it's a duplicate of bug #1239233: that bug is talking about problems with playback over HDMI, while my problem is that HDMI is being used at all (I only have built-in speakers, so I'm pretty sure HDMI is not what I want).

[penalvch (penalvch)]

Calidonia Hibernia, please do not mark this a duplicate of another bug or vice versa. As well, if you have a belief it may be a duplicate, please explain in full technical detail why this would be, with offending commit.

Dima Ryazanov, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[Dima Ryazanov (dima-gmail)]

I've upgraded to the mainline kernel 3.12.0-031200-generic, and looks like it's fixed.

[penalvch (penalvch)]

Dima Ryazanov, thank you for your comment. Given Trusty is rebased on upstream/mainline 3.12.4, could you please test it and advise if the issue is resolved in it?

[Dima Ryazanov (dima-gmail)]

Turns out, the bug is *not* fixed in 3.12.0-031200-generic - just doesn't happen as frequently, I guess.
I will try 3.12.4 now.

[Dima Ryazanov (dima-gmail)]

Just upgraded the kernel to 3.12.4-031204-generic - and the bug still happens.
The HDMI audio is selected by default. I'm using a Dell XPS 13 laptop, which doesn't even have an HDMI output, so there's no audio at all.

[Dima Ryazanov (dima-gmail)]

Is there a way to just disable HDMI? Or lock the configuration? All I'm asking for is for Ubuntu to not mess with the settings that already work.

See comment #2; I cannot collect the logs.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

  With the recent release of this Ubuntu release, would like to confirm if this bug is still present. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Dima Ryazanov (dima-gmail)]

Looks like it's fixed. I've been running Ubuntu 14.04 for a while now, and haven't seen any problems.

[penalvch (penalvch)]
