no sound since upgrade to gutsy with pci id 10b9:5461

[feanor]

After an upgrade to gutsy, sound works at first but fails after an additional update.
I have added output as requested in "debugging sound problems" as a text file.
Thanks a lot for taking care of this :-)

greetings,

I have resolved this bug for me by downgrading to feisty. Sound definitively works in feisty.

Same probleme. Dont know how fix it.
Will try to find / re-install the correct driver.

Alsa propose only 5451 (http://www-old.alsa-project.org/alsa-doc/index.php?vendor=vendor-ALi#matrix) ... doesn't work.
Bug fixed by "Method E: Patch to add support for Realtek ALC268 Codec to Alsa 1.0.14" (https://wiki.ubuntu.com/Gutsy_Intel_HD_Audio_Controller)

I have also had the same problem. I have two soundcards. In feisty, the sound worked, in gutsy not.

 aplay returned following:
ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'defaults.pcm.dmix.device'
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:3982:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default

So I decided to delete my configuration files:
rm .asoundrc .asoundrc.asoundconf

The sound immediatelly started working! But I would prefer if the files were deleted by the upgrade script rather than struggling myself to find the reason.

Just to give you more information, here is the diff between my correctly working gutsy (left) and the original feisty configuration file. In the older alsa version, the definitions like "defaults.pcm.device" were probably not yet mandatory:
15,21c15,17
< defaults.pcm.dmix.max_periods 0
< defaults.pcm.dmix.rate 48000
< defaults.pcm.dmix.format S16_LE
< defaults.pcm.dmix.card defaults.pcm.card
< defaults.pcm.dmix.device defaults.pcm.device
< defaults.pcm.dsnoop.card defaults.pcm.card
< defaults.pcm.dsnoop.device defaults.pcm.device
---
> defaults.pcm.dmix_max_periods 0
> defaults.pcm.dmix_rate 48000
> defaults.pcm.dmix_format S16
54,56d49
< defaults.namehint.showall off
< defaults.namehint.basic on
< defaults.namehint.extended off

It unfortunately appears that this bug is not yet resolved. Does this issue still exist in the Hardy Heron 8.04 LTS release? If so, the Intrepid Ibex 8.10 Alpha2 is also scheduled for release today. It will appear at the following when available: http://www.ubuntu.com/testing/intrepid/alpha2 . It contains the actively developed 2.6.26 Ubuntu kernel. It would be great if you could test this upcoming release via a LiveCD and verify if the issue still exists. If so, please include the appropriate debugging information as outlined at https://wiki.ubuntu.com/DebuggingSoundProblems . Thanks in advance.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

The 18 month support period for Gutsy Gibbon 7.10 has reached its end of life -
http://www.ubuntu.com/news/ubuntu-7.10-eol . As a result, we are closing the
linux-source-2.6.22 kernel task. It would be helpful if you could test the
new Jaunty Jackalope 9.04 release and confirm if this issue remains -
http://www.ubuntu.com/getubuntu/releasenotes/904overview. If the issue still exists with the Jaunty
release, please update this report by changing the Status of the "linux (Ubuntu)"
task from "Incomplete" to "New". Also please be sure to run the command below
which will automatically gather and attach updated debug information to this
report. Thanks in advance.
