Hi everybody,

Till today, I had issue with internal mic which was undetected (Dell G3 3590)

Few months ago, I updated my Ubuntu to latest LTS, 20.04.1
That didn't help. But... after a bunch of regular updates and upgrades, today, I have deleted line which "fixed" issue with dummy output/input.

file: sudo vim /etc/modprobe.d/alsa-base.conf
deleted line: options snd-hda-intel dmic_detect=0 => note that this command turns off mic (if I understand this part correctly dmic_detect=0)

After restart, internal mic works :)

Try it out! I hope that this bug is resolved for all of you.
Do not forget to update your Ubuntu to latest LTS. For me, this action passed without error.
