Microphone not work

The zoom microphone does not work on my laptop. The zoom speakers do work.

I have carried out trouble shooting and in my laptop settings it gives zoom permission to use it. I have tried all the trouble shootings, none solved this issue.

My laptop microphone has been tested and it works. There is no reason why after checking everything is correct why there is no sound from the microphone. When I test it it is silent.

Any suggestions?
