Re: Microphone stops working when switching on webcam

My micro stops working when I switch on built-in webcam on my laptop

Seems like you now have two microphones. One of them is probably part of the webcam? My guess is you can use some tools like 'alsamixer' to switch to and fro and manually select the prefered audio source?
