CONFIG_SND_HDA_INTEL regression on 2.6.37-rc3 - no audio

CONFIG_SND_HDA_INTEL regression on 2.6.37-rc3 - no audio

[Luis R. Rodriguez]

I just booted 2.6.37-rc3 and noticed my sound with
CONFIG_SND_HDA_INTEL stopped working, I get no audio at all. Is this a
known regression? I can bisect if not.

Note that on some ThinkPads, there is an additional output mixer that is
not always exported to ALSA. Please make sure that your hardware volume
is unmuted and at a reasonable volume.

Could you use alsa-info.sh to gather your codec files, system DMI, etc
please?

(The only audio regression in 2.6.37 that I'm aware of was Realtek
ALC269-related and has already been fixed. It left me without volume
control until -rc3)

A couple others (both AC'97 and HDA) have popped up since 2.6.32, and
they're resolve as they're reported.

I haven't heard of such a regression, so far.  Which kernel did work?
2.6.37-rc2 worked?  After rc2, there aren't so many commits for
HD-audio, so if it's a regression, it's likely in another deeper
part, I guess.


thanks,

I reported a 2.6.36 to 2.6.37 regression in HDA_INTEL for my Vaio Z to
the bugtracker:

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5216

it's perfectly reproducible - I have a 2.6.36 and a 2.6.37 kernel both
installed on here, I have to boot the 2.6.36 one for sound to work and
the 2.6.37 one for bluetooth to work. =)

Could you update the kernel bugzilla 25002 instead, as mentioned in
HD-Audio.txt?
    https://bugzilla.kernel.org/show_bug.cgi?id=25002

I see something similar... but oss emulation still works as expected
for me. Can you try it that way? (/dev/dsp).
