- external mic is now working (!), when jack is plugged-in, it corerctly asks what device have I connected (headset or headphones?)
- internal mic is not working, though :(
4) it (does not) works with pci=nocrs, too:
================================
❱ cat /proc/cmdline
initrd=\EFI\Pop_OS-a99686bf-c48a-464b-af3a-25f67847049a\initrd.img root=UUID=a99686bf-c48a-464b-af3a-25f67847049a ro quiet splash pci=nocrs snd_intel_dspcfg.dsp_driver=1 snd_hda_intel.model=alc255-acer
So, this solution is not very practical, because when I do not have headset available at the moment, I cannot use internal microphone :(
I've made a new test, currently on POPOS 21.04, kernel 5.13:
❱ uname -rv 21.04~930e87c- Ubuntu SMP Fri Sep 17 00:24:58 UTC
