I am having problems with internal microphone on elementary OS 5.1 Hera(based on Ubuntu 18.04.3 LTS). Linux is not detecting the internal microphone. If I plugin a headphone with microphone, it will be working fine. Also there is no problem with the internal speakers.
I have tried all the methods specified here.
Also I have tried editing
options snd-hda-intel model=dell which didn't worked as well.
Following are the output for
head -n 1 /proc/asound/card0/codec*:
==> /proc/asound/card0/codec#0 <== Codec: Realtek ALC3254 ==> /proc/asound/card0/codec#2 <== Codec: Intel Kabylake HDMI
Here is my Alsa logs.
Do anyone have any ideas to solve this?
