snd_hda_intel won't load on 2.6.20-16-generic

[Christopher Armstrong]

Binary package hint: linux-image-2.6.20-16-generic

My sound doesn't work with the 2.6.20-16-generic kernel. It does work with the 2.6.20-15-generic kernel. All modules except snd_hda_codec and snd_hda_intel are loaded when I boot 2.6.20-16-generic.

These are the versions of kernels I'm using:

radix@haruko ~% dpkg -l |grep linux-image-2.6.20
ii linux-image-2.6.20-15-generic 2.6.20-15.27 Linux kernel image for version 2.6.20 on x86/x86_64
ii linux-image-2.6.20-16-generic 2.6.20-16.32 Linux kernel image for version 2.6.20 on x86/x86_64

[mhyk (jackassinthebox)]

I also exactly have the same problem as yours...

[Christopher Armstrong (radix)]

By the way, I upgraded to the gutsy prerelease on this machine and my snd_hda_intel started working again. This is on kernel 2.6.22-12-generic.

[mhyk (jackassinthebox)]

what's new with the kernel? actually im having a lot of problem other than the sound with my current kernel.

[Leann Ogasawara (leannogasawara)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. For a short description of changes that go into each kernel release you can refer to the following:

https://launchpad.net/ubuntu/+source/linux-source-2.6.22/

As Christopher mentioned, care to update to the latest kernel release (2.6.22-14) and verify this is still an issue or if this is resolved? If this is still an issue please attach the following information outlined here:

https://wiki.ubuntu.com/KernelTeamBugPolicies

Thanks in advance!

[teledyn (garym-teledyn)]

Confirmed that this situation exists in Gutsy, but it didn't exist with Feisty -- with the Feisty release, I only had to compile the ALSA from the current snapshots (I used alsa-driver-hg20070911), but with Gutsy the ALSA snapshot compiles without incident but fails with a string of snd_pcm and other snd_* unknown symbols. Very distressing.

[teledyn (garym-teledyn)]

oh, just to confirm, this is with Linux 2.6.22-14-generic -- I simply let the auto-update tool upgrade my Feisty first to all the latest packages, and then today let it make the jump to 7.10.

[Leann Ogasawara (leannogasawara)]

Can you try installing the linux-backports-modules package (if it isn't installed already). Thanks.

[Brian Murray (brian-murray)]

We are closing this bug report as it lacks the information, described in the previous comments, we need to investigate the problem further. However, please reopen it if you can give us the missing information and feel free to submit bug reports in the future.

[bbull (bbull06)]

I was having this same issue with the 2.6.22-14-generic kernel and following the recommendation of installing the linux-backports-modules package resolved it.

[Kevin Dalley (nereocystis)]

Another solution.

After running:

sudo module-assistant auto-install alsa

I ran:
  sudo mv /lib/modules/2.6.24-19-generic/updates/snd-hda-intel.ko /lib/modules/2.6.24-19-generic/updates/snd-hda-intel.ko-hide

and then rebooted.

This hides the snd-hda-intel.ko from linux-ubuntu-modules-2.6.22-14-generic and uses the one in alsa-modules-2.6.22-14-generic.
