Bug Description

Binary package hint: linux-image-2.6.32-28-generic

Upgrading from 2.6.32-27-generic to 2.6.32-28-generic breaks HDMI audio output.

Test case: When running the command: aplay -D plughw:0,3 /usr/share/sounds/alsa/Noise.wav
a) with kernel image 2.6.32-27-generic, I hear the noise
b) after applying all updates, including installing kernel image 2.6.32-28-generic, I do not hear the noise,
c) after manually removing only the new kernel, keeping all other updates, I hear the noise again.
The same is true for any other way of playing sound via HDMI.
The problem does not occur with analog output, only with HDMI output.

My system: Xubuntu 10.04.1 LTS (64 bit) on Gigabyte GA-H55M-US2H

Output of "aplay -L":

Thank you for taking the time to report this bug and helping to make Xubuntu better. 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.

The reporter is indicating that this used to work with one kernel in Lucid and now it doesn't. I'm not sure testing the upstream kernel, for a bug with a regression in a stable release is really necessary.

the problem persists; i.e. these kernels do not play sound via hdmi, too.

I just found a workaround: After entering:

sudo cp -p /lib/modules/2.6.32-27-generic/updates/alsa/snd-hda-codec-intelhdmi.ko /lib/modules/2.6.32-33-generic/updates/alsa/snd-hda-codec-intelhdmi.ko

HDMI output works immediately, without reboot.

Currently linux-backports-modules-alsa-lucid-generic and its dependencies, i.e. currently linux-backports-modules-alsa-2.6.32-33-generic. But the problem started, when the following packages were added:

linux-headers-2.6.32-28 (2.6.32-28.55)
linux-headers-2.6.32-28-generic (2.6.32-28.55)

I.e. linux-backports-modules-alsa-* was not touched at the moment of the start of the problem.

I trust you already tried removing all linux-backports-modules-alsa-* packages? Specifically, have you tried
a) booting 2.6.32-27 with no alsa-backports installed
b) booting 2.6.32-33 with no alsa-backports installed

If the 2.6.32-28 kernel update didn't come with the corresponding linux-backports-modules-alsa-$version package, a change in audio behaviour sounds reasonable.

(Note: always report a bug from the *non*-working kernel so the proper logfiles get added)

@Julian: Thank you very much, your comment most probably contains the solution for this bug.

I just re-tested all combinations:

kernel 2.6.32-27 without alsa-backports: HDMI sound does NOT work.
kernel 2.6.32-27 with alsa backports: HDMI sound DOES work.
kernel 2.6.32-33 without alsa-backports: HDMI sound does NOT work.
kernel 2.6.32-33 with alsa backports: HDMI sound DOES work.
(The hack described in my previous post was not needed.)

> If the 2.6.32-28 kernel update didn't come with the corresponding linux-backports-modules-alsa-$version package, a change in audio behaviour sounds reasonable.

As far as I can see: That's it! According to my Synaptic chronics, on 2011-01-27 01:15 indeed only linux-image-* but not linux-backports-modules-alsa-* were updated to 2.6.32-28. After submitting the bug report above, I reverted to kernel 2.6.32-27 and inhibited any later kernel update by uninstalling all virtual packages depending on the most recent kernel version number. So linux-backports-modules-alsa-2.6.32-28 (which must have been released later) has never been installed on my system.

Solution for my problem: Defer all future kernel updates until the corresponding alsa backport update is also available and always install them together.

Thanks!

My last sentence can be misunderstood: I will defer the updates, not the Canonical kernel team :-)

Right, that would explain why the new alsa-backports package wasn't pulled in automatically after it was released.
Note that this is only an issue if the kernel ABI changes. So updating 2.6.32-33 shouldn't cause any issues, but when installing 2.6.32-34 make sure that the new alsa-backports package is available as well.

Now that you know the reason for this issue: if you notice any significant, reoccuring delays - don't hesitate to open a bug about it. Maybe there's a way to improve the workflow and/or packaging.

Hi, Julian,

Thank you very much for your help!

I'll have an eye on it :-)
