linux upgrade 6.16.10.artix1-1 -> 6.17.1.artix1-1 seem to break audio

Hello, I'm not sure if this change in particular:

Code: [Select]
[2025-10-11T23:30:08-0600] [ALPM] upgraded linux (6.16.10.artix1-1 -> 6.17.1.artix1-1)

But I can't really tell, a reboot didn't help.  The audio driver is "snd_hda_intel":

Code: [Select]
00:1f.3 Multimedia audio controller: Intel Corporation Cannon Lake PCH cAVS (rev 10)
    Subsystem: Hewlett-Packard Company Device 860f
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
    Latency: 64
    Interrupt: pin A routed to IRQ 16
    IOMMU group: 11
    Region 0: Memory at 404a108000 (64-bit, non-prefetchable) [size=16K]
    Region 4: Memory at 404a000000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: <access denied>
    Kernel driver in use: sof-audio-pci-intel-cnl
    Kernel modules: snd_soc_avs, snd_sof_pci_intel_cnl, snd_hda_intel

I'm about to revert to 6.16.10 to see if that helps, and also to keep working...  We'll see if that helps.

Effectively, downgrading linux (the kernel) together with its headers to 6.16.10 brought audio back

Jus in case, the difference is that with 6.16.10 I get:

Code: [Select]
m1:~:% ls /sys/class/sound/
card0@  controlC0@  hwC0D0@  hwC0D2@  pcmC0D0c@  pcmC0D0p@  pcmC0D3p@  pcmC0D7p@  pcmC0D8p@  timer@

whereas with 6.17.1 I get:

Code: [Select]
m1:~:% ls /sys/class/sound/
timer@

Just the timer.  And the driver now loads, because it's found:

Code: [Select]
00:1f.3 Multimedia audio controller: Intel Corporation Cannon Lake PCH cAVS (rev 10)
    Subsystem: Hewlett-Packard Company Device 860f
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
    Latency: 64
    Interrupt: pin A routed to IRQ 193
    IOMMU group: 11
    Region 0: Memory at 404a108000 (64-bit, non-prefetchable) [size=16K]
    Region 4: Memory at 404a000000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: <access denied>
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel, snd_soc_avs, snd_sof_pci_intel_cnl

As opposed to linux 6.17.1, which you can see the difference in:

Code: [Select]
Kernel driver in use: snd_hda_intel

vs:

Code: [Select]
Kernel driver in use: sof-audio-pci-intel-cnl

Hmm, that is strange that the module didn't load.
Quote
$ cd /usr
find -name '*snd-sof-pci-intel-cnl*'
/usr/lib/modules/6.17.1-artix1-1/kernel/sound/soc/sof/intel/snd-sof-pci-intel-cnl.ko.zst
The module appears to be present in the package. Maybe try modprobe to manually load it.

I believe that's not the module it should load, but rather snd-hda-intel, that's the one I remember being loaded for quite some time.

I believe it might be firmware.  The current series of firmware for linux we have is:

Code: [Select]
system/linux-firmware 20250917-1 [installed]

But on arch the firmware  series version is 20251011-1.  It might be, can' tell for sure, I'll try Tonight or when having the chance.

As the new FW is on gremlins, it was an easy trial, and upgrading all linnux-firmware present did not help a bit with 6.17.1.

On some HP systems these Sound Open Firmware packages from sof-bin are required for audio:

sof-firmware 2025.05.1-1
sof-tools 2025.05.1-1

I would install linux-lts for sound, so you can keep 6.17.* for further updates and tests.

BTW, I do have sof-firmware installed.  This is an old laptop, and apparently it doesn't support any of the modern drivers.  Before I had:

Code: [Select]
% bat /etc/modprobe.d/audiofix.conf 
options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes

That is no longer working.  What I need now (I haven't tested the mic, which is how I needed that before) is:

Code: [Select]
% bat /etc/modprobe.d/audiofix.conf 
# options snd-hda-intel dmic_detect=0 (deprecated)
options snd-hda-intel model=laptop-amic enable=yes
options snd-intel-dspcfg dsp_driver=1

I still tested the non legacy drivers, see:
Code: [Select]
% modinfo snd-intel-dspcfg
...
parm:           dsp_driver:Force the DSP driver for Intel DSP (0=auto, 1=legacy, 2=SST, 3=SOF, 4=AVS) (int)

I bet 0 is what attempted by default, I tested 2 (sst), 3 (sof) and 4 (avs), and they all failed to load their firmware according to dmesg.  So I tried 1, which is the suggestion given by dmesg because snd-hda-intel. dmic_detect doesn't work anymore, and it worked.  So I don't know how sound was detected before, that through snd-hda-intel one could select whether using dmic or not, and apparently depending on that the driver to use was changed or not, and now it's instead done through snd-intel-dspcfg.

Also, the changes leading to requiring dmic_detect were also like the current one, it came with a linux upgrade.  When that happened at that time there were more posts about what to do.  This time I couldn't find anything useful on the web.  Perhaps it's too early.

I need to test the mic, and if it works I'll mark this as solved.  And sorry for the noise.

Mic working as well, so that was it.  Marking as solved.  Many thanks !
