This looks more Firefox related rather than your desktop's issue. Check

Microphone doesn't work

[sterbl.ta]

Don't know how to explain my problem (probably because I am not familiar with 
hardware and sound relation setting). Apology if description of my problem 
looks incompletely. My problem is when attending the online meeting, my 
laptop's microphone never worked at all. 

My laptop is HP 840 G5, and its audio should be 
https://support.hp.com/us-en/document/c05903000#AbT9 


Environment I use:

kernel: 5.2.0-2-amd64
Debian version: bullseye/sid

arecord --list-devices shows

 List of CAPTURE Hardware Devices 
card 0: PCH [HDA Intel PCH], device 0: CX8200 Analog [CX8200 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Checking alsamixer, it looks like ok because microphone is turned on

Following the instruction at 
https://linuxconfig.org/how-to-test-microphone-with-audio-linux-sound-architecture-alsa
 

 for testing my microphone.

1. Record sound produced by microphone 
arecord -d 10 /tmp/test-mic.wav2. Reply the sound recorded 
aplay /tmp/test-mic.wav
I am sure I can hear the sound produced by my microphone. 

Unfortunately when attending all the meeting (such as google meets), even with 
permission is granted (allowing microphone and camera to be used temporary) my 
microphone never function (so people in the meeting never heard my voice). 

I suppose this could be something I miss or I am not aware. But the problem i 
do not know where to check the possible root cause, and fix it. 

I appreciate any suggestions!
