Alsa and Pulseaudio not recognizing mic in analog headset

Hey all,
I have Arch Linux (5.11.15-arch1-2) on Acer Spin 5.
When I plug in my stereo mic hadphone into the 3.5 mm jack, alsa recognizes the headphones but not the mic. Also a regular popping sound can be heard in the headphones.

I tried troubleshooting online and figured out it was a codec issue and tried appending the headset-mic codec but it doesn't work. COnfiguring with hdajackretask also doesn't work .
i tried out the solution in the following forum,  https://superuser.com/questions/1312970 … e-und-alsa
But it doesn't work

The forum suggests to add codecs for the sound card,
but I feel as if i would have to install them first?
instead of just appending in /etc/modprobe.d/alsa-base.conf....
I tried searching AUR for codecs but i cound't find anything related...

some snippets:

$ cat /proc/asound/card*/codec* | grep Codec
Codec: Realtek ALC295
Codec: Intel Kabylake HDMI

 $ lspci| grep -i audio
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

 $ acpi_listen
jack/headphone HEADPHONE unplug
jack/headphone HEADPHONE plug 

since it is an hardware recognition issue i think it is a problem regarding codec/drivers?
Also there is nothing wrong with headphone or laptop because it used to work with windows which came preinstalled...

I have been trying to fix this since weeks! any help would be appreciated !

Re: Alsa and Pulseaudio not recognizing mic in analog headset

Did you reboot after setting a new model via /etc/modprobe.d ? In general most codecs are already present and you manipulate which one is loaded via the model= line but that will only trigger on module reload.

Also maybe post some more information like what is detected where do you see/surmise it isn't working, what's your output for

amixer -c0

but yes in general, this is something that often doesn't quite work right.

Yes, V1del i did reboot after every possible permutation...
I cannot see the mic input in amixer or pavucontrol also I have seen people post the output of acpi_listen and there they get an output like:

$ acpi_listen
jack/headphone HEADPHONE plug
jack/microphone MICROPHONE plug 

while i only get the headphone event notif....
the output for amixer -c0 shows some mysterious 'Capture' which is disabled / off and gain is -17 could that my my headphone mic?
