My ubuntu 20.04 doesn't recognizes external mic with combo jack entry microphone, i nearly tried everything. Here are some information and things i did.
My codec for sound cat /proc/asound/card1/codec* | grep Codec
Codec: Realtek ALC269VC
sudo lshw -c sound
shows this;

Things i added to the /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=basic
options snd-hda-intel position_fix=1
Model is basic but i tried a lot of things then i found my codecs model in the official documentation of Ubuntu
I tried overriding jack from hdajackretask
but when i change something from there i always get the tee: /sys/class/sound/hwC1D0/reconfig: Device or resource is busy
even when im not running anything on my system(videos, sound etc.)
Is there any other way to solve this or should i buy a jack to usb transformer?
