Chromium - microphone lost in some minutes

P

I'm using Microsoft Teams in Chromium 83.0.4103.116 browser on FreeBSD 12.1 p10.
If I start a voice call - it works, but after some minutes my colleagues cannot hear me. If I restart a call - it works again, but only during some minutes, then I'm lost again. I use internal laptop's microphone, pulseaudio is installed.
Is it a known bug? How can I debug this problem? Is there any way to change microphone used by Chromium from dsp2 (internal) to dsp4 (usb) without changing the default sound device?
Note that I don't have this problem in the native telegram-desktop client (Qt5).
 
Same thing here. After few minutes my colleagues reports they can't hear me because I got robot voice ='D
I'm keep trying to figure out a way to fix this.
 
I'm on v.87 actually. It did not work with the default backend, I rebuilt the port with pulseaudio - it does work neither. On call it says "Your microphone is muted", but the controls on page say it is not muted. So, no way to unmute it.

I've done some tests, it seems that there are two different problems (in PulseAudio version):
1. The channel to use for microphone input is not taken from settings, the default one is used. If I force the good channel on PulseAudio level - it works... for 1-2 minutes
2. After 1-2 minutes the microphone is muted. I cannot unmute it on PulseAudio level, ON/OFF does not help neither.
The same configuration perfectly works for Telegram.
