Microphone not working on Mac – how to fix?

Issue: Hello. I have a problem that I cannot find the solution to. The Macbook Pro microphone is not working. I try to connect to my classes, use Discord, Zoom, and other programs, but no one can hear me without additional options like a headset. Checking issues with system settings, but there is no response and no detected issue. Can you help me fix this permanently because all the found solutions are working temporarily?
