microphone problems

For a few days I have had problems with the microphone since when I speak people say they do not listen to me. but I do listen to them, I have tried all the possible solutions and nothing has worked, I thought it could be my headphones but I have tried other meeting programs and they work correctly. Apparently zoom is the only one that refuses to recognize them, plus it doesn't allow me to activate the microphone now.
I've already tried the troubleshooter.
Using other headphones.
Using other versions of zoom.
And nothing has worked.
