Your laptop internal microphone doesn’t work on Linux? Here is the solution!

Openalsa-base.conf from/etc/modprobe.d/

and add this line: “options snd-hda-intel model=dell-vostro enable=1 index=0

Or, you can try to just mute right mic channel (yeah yeah, all internal microphones in all laptop as usual cheap af, so they are in mono, and Linux sees it like in “stereo”, that’s why you have this problem).

Install pavucontrol: sudo apt-get install pavucontrol

Go to the “Input Devicestab

Click on the lock icon

And mute right channel (Just set right channel to the left side)

Don’t forget to disable “ Automatically adjust microphone settings” in Skype.

And if you use Chrome for any audio/video chat, I have a bad news for you.

“ Unfortunately the WebRTC implementation in Chromium comes with a handy “feature” called Automatic Gain Control that tends to screw with your microphone volume. Unless the web app itself gives you an option to disable it, there is otherwise no way turn it off, and Chrome developers don’t want to add a global “off switch” for it.” Source.
