ThinkBook 16 G7+ ASP 21Q5: Built-in microphone does not work.

Kernel: 6.15.5-arch1-1

It has AMD Ryzen AI 9 H 365 w/ Radeon 880M.

$ arecord -l

I have installed:

$  pacman -Q alsa-card-profiles pipewire-alsa
alsa-card-profiles 1:1.4.6-1
pipewire-alsa 1:1.4.6-1

At the end - in telegram the built-in microphone works.
But in other apps: google meet via firefox, zoom, pavucontrol - it does not work.

I'm newby, please help me.

Re: ThinkBook 16 G7+ ASP 21Q5: Built-in microphone does not work.

Maybe should I give some additional info?

I have tryed from this  https://bbs.archlinux.org/viewtopic.php?id=294307

echo -e "snd-pci-ps\nsnd-soc-ps-mach" | sudo tee /etc/modules-load.d/sound.conf > /dev/null

But It doesn't take effect.

Re: ThinkBook 16 G7+ ASP 21Q5: Built-in microphone does not work.

I have update:

If I block snd-soc-dmic

  echo -e "blacklist snd-soc-dmic" | sudo tee /etc/modprobe.d/blacklist-sound.conf > /dev/null 

My internal mic start working.

But I get errors:

kernel: acp_mach acp-pdm-mach: devm_snd_soc_register_card(acp-pdm-mach) failed: -517
kernel: acp_mach acp-pdm-mach: devm_snd_soc_register_card(acp-pdm-mach) failed: -517
kernel: acp_mach acp-pdm-mach: devm_snd_soc_register_card(acp-pdm-mach) failed: -517
kernel: acp_mach acp-pdm-mach: devm_snd_soc_register_card(acp-pdm-mach) failed: -517
kernel: acp_mach acp-pdm-mach: devm_snd_soc_register_card(acp-pdm-mach) failed: -517

After I update my blacklist-sound.conf:

blacklist snd-soc-dmic

blacklist snd_acp_legacy_mach
blacklist snd_acp_mach
blacklist snd_soc_nau8821

blacklist snd_pci_acp6x
blacklist snd_pci_acp5x

The errors are gone.
