Comment 41 for bug 1845797

I just checked the solution from this thread https://bugzilla.kernel.org/show_bug.cgi?id=201251 and it worked for DMIC, it appeared.
So what was needed in my case is
options snd_pcm max_alloc_per_card=41943040
I tried in ArchLinux 5.11.7.
Only issue is that  the recording level too quiet and in fact is non operational ), but i think it is a great step forward any case. It is the first time when i saw microphone in Linux settings on my Lenovo Yoga C930 )
You should use no snd_intel_dspcfg dsp_driver options or use only
options snd_intel_dspcfg dsp_driver=2
Would be great to find solution to fix the level of recording now.
