Hi, I've recently installed Zorin OS on my mom computer.
Everything was fine until I tried to make a meet (Google Meet, Zoom or Jitsi Meet, same result) over Chrome.
The browser ask me to give permission to the web camera and the microphone, and that’s what I did.
There was no error on the screen, but on the other side no one was hearing my voice.
Double check the browser permissions for the mic ... was OK.
I increased the mic volume, and all I get was a noisy background.
Reading on many forums I found that there is an inversion issue between the internal microphone and the external.
I've tryed several options:
-
Enable the internal audio monitor in the pavucontrol app, and mutting the right side channel ... did't work.
-
Download and install the alsa-hda-dkms package looking to mute the "Inverted Internal Mic", but I can't see the inverted internal mic in Alsamixer.
-
Something actually did work, but the fix get lost when I restart the browser (and obviously also when I restar the whole computer) was, with the Alsamixer open, make the set and unset de external mic from pavucontrol app. It make it work into de Chrome.
-
I added in the /etc/modeprobe.d/alsa-base.conf these two properties:
options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
Reboot
Didn't work -
I created new file /etc/modprobe.d/blacklist-local.conf and add the following line in it:
blacklist snd-soc-dmic
Reboot
Didn't work
