Audio Error. Microphone not found

I am using Manjaro Linux and I just installed jitsi-meet-desktop-bin 2.4.2-1 powered by Electron from AUR.
The program starts and works, but an error message tells me that it cannot find the microphone.
I use a Logitech QuickCam Pro 9000, that works perfectly well with Zoom.
What is wrong. How can I solve this?

check if your hardware is compatible by going to test.webrtc.org with chromium; if the microphone works here, it’s a jitsi-meet problem and add an issue to the jitsi-meet github site; if not it’s a hardware or driver or webrtc problem.

test.webrtc.org could not find the microphone either.
So, I have added an issue to the jitsi-meet github.
