[REGRESSION] "ALSA: HDA: Early Forbid of runtime PM" broke my laptop's internal audio

[Michael Catanzaro]

Hi,

On my System76 Gazelle Pro (gazp9) laptop, internal audio broke after 
upgrading to kernel 5.10.

The laptop's speakers produce no sound. Audio from headphones still 
works fine. A quick test is to visit GNOME System Settings -> Sound -> 
Output, select Test, click Front Left or Front Right and notice there 
is no sound. I tested a mainline kernel revision from yesterday 
(5.11-rc5+) and the regression is not yet fixed. I bisected the 
regression to "ALSA: HDA: Early Forbid of runtime PM":

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a0645daf16101bb9a6d87598c17e9a8b7bd60ea7

I created a downstream bug report here, including some bits from dmesg 
that may or may not be relevant in comment #2:

https://bugzilla.redhat.com/show_bug.cgi?id=1918933

Audio devices:

$ lspci | grep -i audio
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core 
Processor HD Audio Controller (rev 06)
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset 
High Definition Audio Controller (rev 05)

OS: Fedora 33

I'm happy to provide any additional required info or test patches if 
you CC me, since I'm not a kernel developer and am not subscribed to 
these lists. Thanks.

Does reverting just this patch fix the issue you are seeing?

Can you share the full dmesg and also let us know which codecs are on your system?

Thanks, good to hear.

Then I think we can drop the entry from power_save_denylist in
hda_intel.c.  Could you try that it still works with the patch below?


thanks,

Hi,

This patch works fine on my laptop. I have no clue whether that means 
it's really safe to remove the quirk. I've never noticed any clicking 
noise myself, but I understand it has been a problem for other System76 
laptops.

If you find no noticeable problem, that's fine, and I believe we can
drop from the deny list.  But it's no urgent issue and fit well as a
5.12 material.  Will submit a proper patch later.


thanks,

For me applying patch 4961167bf7482944ca09a6f71263b9e47f949851 on top of 5.10.12 fixes audio, but the above quoted patch applied to 5.10.12 does NOT fix audio.  What I mean by fixes:
Audio works normally on 5.4.94, and on 5.10.12 with patch 4961167 applied.
I hear no audio from the laptop speakers on 5.10.12 and 5.10.12 with the above quoted patch applied.  Opening pavucontrol shows a graphical response in the meter, but no audio is heard from the speakers.  I did not test plugging in headphones and did not test audio over HDMI.

I have a System76 Gazelle Pro 7 (gazp7).

Re: [REGRESSION] "ALSA: HDA: Early Forbid of runtime PM" broke my laptop's internal audio

[藍挺瑋]

I am not sure if I should join this old thread, but it seems that I saw the same
issue on my ASUS B23E laptop. It couldn't produce any sound after upgrading to
Linux 5.10, and 'git bisect' shows it was broken by the same commit
a0645daf16101bb9a6d87598c17e9a8b7bd60ea7.

I have tested the latest master branch (v5.14-rc4-322-gcceb634774ef) last week.
It still had no sound. If I reverted the broken commit, sound worked.

Thanks for the report.  A quick workaround be a patch like below.
Could you verify whether it fixes the problem?

Thanks.  Now I submitted a final patch and will merge it for
5.14-rc7 pull request.
