[patch] snd-hda-intel not working with alsa 1.0.14

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at [WWW] https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux-source-2.6.22

Sorry for not adding the right package myself.

This patch is committed in 2.6.23, here is some more information: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=df802952b723cdb08f2f8a3cba396c357290850b

Thanks.

By "not working" did you mean that you can't load the snd-hda-intel module? I just did an upgrade from Feisty to Gutsy and I am unable to modprobe snd-hda-intel, even though it is installed. Just wondering if this is the same problem you had.

Hi Cody,

Yes that's right, I couldn't modprobe snd-hda-intel, and the following message appeared in dmesg:

[ 33.360190] stac92xx_auto_fill_dac_nids: No available DAC for pin 0x15

Do you get something similar?

Patch committed. Will try to get an upload for beta, otherwise it will be included for release.

@Ben Collins: Please could you check if this Bug - and the patch related to it - does affect Bug #131133 in any way?

Sound on my Macbook Pro seemed to be working immediately after I upgraded to gutsy as of RC1.
With yesterdays kernel update sound has ceased to work:

Figured this one out. The bad sound driver was coming from linux-backports-modules.

I have the same error on my mabook pro, except for the azx_get_response line. I have gutsy now, but I use my own kernel 2.6.23-kamikaze4 (which has alsa 1.0.15). It didn't work for me on 2.6.22 ubuntu kernel either, I had to do some ubuntu specific update-modules alsa stuff that I don't remember, and have no idea what means.. anyone know how to fix this?

The patch referenced in this bug report was included in the linux-ubuntu-modules-2.6.22 package. I'm marking this report as 'Fix Released'. If you are still experiencing problems, please test against the latest Hardy Alpha Release (http://cdimage.ubuntu.com/releases/hardy/) and verify this issue still exists. If so, please open a new report against the 'linux' source package since as of the Hardy release the kernel source package naming convention changed from just "linux-source-2.6.x' to just 'linux'. Thanks.

The same problem
dmesg:

Sound worked only with acpi=off. In Gusty sound worked without this parameter.
