[HDA-Intel] No digital audio output with latest kernel patch (2.6.35-25-generic-pae)

[Roberto Leinardi]

After the upgrade to the latest kernel patch (2.6.35-25-generic-pae) no sound is played by the Digital Audio Output.

The sound works well with the kernel patch 2.6.35-24-generic-pae.

Confirming. Audio worked properly with 2.6.35-24 but stopped working after upgrade to 2.6.35-25. The only output that worked with latest kernel was HDMI audio. All other outputs did not produce any sound.

Hi JD,

If you could also please 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.

Hi there,

I have got the same problem,

I am not a Linux expert but I have noticed that the package called "upstart" is refusing to update, due to an error with libc6:
upstart:
  Breaks: libc6 (<2.12.1-0ubuntu10.2) but 2.12.1-0ubuntu10.1 is to be installed

I am wondering if this has to do something with it, but knowing how many package depend on libc6 I wouldn't be surprised

Thanks

G

I believe my bug (705405) is a duplicate of this one. I have the same audio device (ICH10, 8086:3a3e) and lost audio somewhere between 2.6.35-24 and 2.6.35-25. I am about to test mainline 2.6.35.10 and will check back in in a few minutes.

[squarooticus (krose)]

Upstream kernel 2.6.35.10 has the same problem, so this is not Ubuntu-specific. This is critical enough that I suspect it has been fixed in a more recent upstream kernel version, so I am going to try some variant of 2.6.38.

[Sparafucile (derrick-everett)]

I lost digital sound output on my 64-bit computer a few days back, apparently with the upgrade to kernel 2.6.35-25. I have tried various things in the hope of getting sound back, including upgrading to the next kernel 2.6.35-26 and updating the alsa drivers, uninstalling and reinstalling pulseaudio, etc., but so far nothing helps. My audio card is described by lspci as follows:

00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller

[squarooticus (krose)]

Sparafucile: sounds like the same bug. FWIW, this problem still exists with mainline kernel 2.6.38, so the problem is neither Ubuntu specific nor, as yet, solved.

[Roberto Leinardi (leinardi)]

Does anyone have news?

[enb (elitenoobboy)]

This happens with upstream kernels as well, including 2.6.38. Trying kernel specific alsa driver dev releases from the audio dev ppa does not fix the problem for me either.

[enb (elitenoobboy)]

This bug might be related to this:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/704401

From that page, it looks like adding
options snd-hda-intel model=6stack-dig
to /etc/modprobe.d/alsa-base.conf might fix it.

[squarooticus (krose)]

Indeed, that solves it for me. Thanks, enb.

[Lee Burch (ltburch2000)]

Yes, worked for me too.

[rerooting (richard-flywheelcollective)]

confrimed that #11 works for me as well
