after clean install pop os, PCI audio card works fine...but headset microphone can not be detected(acer a515-56) and not working.
I added these to end of /etc/modprobe.d/alsa-base.conf
# Headset mic fix
options snd-hda-intel dmic_detect=0
options snd-hda-intel model=alc255-acer
headset microphone work fine,but PCI audio card microphone is gone.
