I have a webcam with a built-in microphone, and when I want to use it, even though it detects it, only the video works, not the audio, so the built-in microphone does nothing.
I'm using version 11 of Debian, although I remember that when I used Ubuntu 20.04 it didn't work either.
And I am sure that I am using the microphone of the WebCam
