No audio after upgrading to 5.15.25-hardened1-1-hardened

I have my system updated to
Code: [Select]
5.15.25-hardened1-1-hardened
kernel. Since then I am not able to hear any audio using any application:
Code: [Select]
mpv, browser
etc., However, booting
Code: [Select]
linux 5.16.10.artix1-1
doesn't have any problem. Could anyone shed some light how to troubleshoot/fix this issue? or this is a bug?

Many thanks in advance.

I'd start by comparing the dmesg output from 5.15.25-hardened1-1-hardened vs linux 5.16.10.artix1-1

Well, for starters, what are the audio devices permissions under /dev in -hardened?

I see no difference, except the order of booting, from the dmesg output. The outputs are given below for references.

I have also observed the system's responsiveness has slowed after the latest kernel upgrade. Meaning, application start times and boot times have increased for both the kernels: Linux-5.15.25 and Linux-5.16.10. I am still facing the issue.

To be honest my advice would be to go back to using the regular artix kernel where things worked.
Just to keep things simple.

I've been using Linux a long time and avoid such things as hardened kernels, selinux and apparmor, as they can cause problems I can do without, and I'm content with the security of my single user home system. Over 20 years, no malware, no viruses, no intrusions, AFAICT.

I can't reproduce, I have sound when using mpv or my browser and you provide no log/error.
Are you sure it isn't an audio server error?

No error or anything. The sound just doesn't work. It happens with firefox (youtube) and mpv. It is most likely with the kernels as the sound just works fine with Linux-5.16.10 (standard full kernel).

If there is an error, mpv would output it. You can try to collect its stdout and stderr to a file:
Code: [Select]
mpv some_file.ogg >mpv.log 2>&1

Also check if the volume is set to some sane value (not zero) and is not muted.

Can you try playing some audio and during that, post output of:
Code: [Select]
sudo fuser -v /dev/snd/*
This one outputs nothing while I am playing an mp3 file.
Quote
Also provide the output of
Code: [Select]
alsactl init
and try playing some audio after that.
No difference after initiating.

Any help would be much appreciated.

You still have the issue with the latest hardened kernel?

I have a similar problem.  I just installed

Code: [Select]
linux 5.16.1-artix1-1

And sound isn't working, just as for artik.

Attempting to run alsafixer gives the errors:

Code: [Select]
ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory

ALSA lib control.c:1528:(snd_ctl_open_noupdate) Invalid CTL default
cannot open mixer: No such file or directory

Also
Code: [Select]
aplay -l
gives
Code: [Select]
aplay: device_list:274: no soundcards found...

And
Code: [Select]
sudo dmesg | grep -iE 'snd|sof'
gives
Code: [Select]
