[alsa-devel] CONFIG_SND_HDA_INTEL regression on 2.6.37-rc3 - no audio
![](https://secure.gravatar.com/avatar/ba45cc474c6f30d2c1b4d63a98ac9283.jpg?s=120&d=mm&r=g)
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. =)

Now I notice someone followed up to the report with some questions, but Mantis didn't notify me! Didn't realize it doesn't do that by default.

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

Will do.

Hi!
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.

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