Is it possible to make secound microphone work?
Pavucontrol doesn't even see it
I was searching for this in the web but I didn't managed to fix this problem and I don't know where I should look for help with such a problem

If you refer to the dual-microphone array, it is handled by ALSA and/or SOF which is not related to WMI at all.

Make sure you've got all relevant *-firmware packages installed (e.g. alsa-firmware, sof-firmware – those are for Arch Linux). Also note that no PipeWire/PulseAudio/ALSA tools will show you the ‘second’ microphone as a separate device or even as a stereo-configured channel, as it is used only internally by the sound card's DSP to implement noise & echo cancellation.

In the case you mean the headphone jack microphone input, then try placing this to /etc/modprobe.d/snd_hda_intel.conf:

options snd_hda_intel model=dell-headset-multi

then rebooting. Might need to try various different models (relevant to the headset mic) from here instead, as that's just the one worked for my Honor MagicBook 14 2021.

Note: might also want to check out huawei-mbx-stereo for better speaker support depending on your device (in case you need it!), but that's risky as mentioned, see more here.
