No sound following a fresh installation

Hi,
I’ve been a Manjaro/Arch user for only about 2 years, so still kind of a newbie. I’ve recently decided to reinstall Manjaro completely, to clean up a bunch of loose files and upgrade my kernel as part of the cleanup.

It turns out, I don’t get any audio from any kernel above 5.15 (i.e. 5.15.102-1-MANJARO).
Running pactl info tells me that the sink used is auto_null. However, installing 5.15 using the default kernel manager makes audio work absolutely fine - all on a fresh installation.

I could provide a bunch of ALSA/PulseAudio debug info, but I don’t think it’s the audio server’s fault. However, here’s my system information using inxi -Fazy:

You could simply say “why don’t you keep using 5.15?”, but I’d like to upgrade, and I don’t think the solution to the problem should be simply avoiding it unless there’s no other way.

Any help would be greatly appreciated!

Hi @mfpx, and welcome!

Welp, according to this page the driver is in the kernel. So it’s possibly not that and the sound server.

Please provide the same inxi output as above, but for both the working and the non-working kernels. Also while you’re at it, please do provide the other outputs you mentioned. It can’t do harm and will possibly help diagnose the problem.

I have a similar problem. New installation and no sound via the docking station. I suspect a very similar problem solution.

There is no data in this probe for sound devices (amixer, aplay and arecord) but inxi’ data is showing ALSA in kernel v6.1 is trying to use Sound Open Firmware driver snd_sof_pci_intel_cnl instead of legacy driver snd_hda_intel used with kernel v5.15

Dummy Output auto_null sink is created by PulseAudio module-always-sink if no ALSA playback devices are detected

Please post more information about ALSA for both kernels v5.15 and v6.1

The URLs to uploaded data will probably need to be posted in preformatted text

Hi @nikgnomic,
Sorry for the “bump”, here’s the information you requested:

5.15 is http://alsa-project.org/db/?f=21150c200ca8f6cf3962f36ee7f8c7b6cff81a40
6.1 is http://alsa-project.org/db/?f=8fe91f3acd8310ef6dbe7d8047523809b9b44258

Thanks for your time!

I’ve tried kernels prior to 5.15 and all version 5 kernels seem to work fine - so it seems that something changed after 5.15 that breaks sound.
My understanding of C and the Linux sound architecture isn’t as good as I’d like it to be, so I can’t really read the code changes.
