When a meeting app cannot hear you, the problem may not be the app itself. The microphone could be muted, the wrong input could be selected, browser permission could be blocked, or the operating system could be routing audio incorrectly.

A browser microphone test is a good first step because it checks whether the browser can access the mic and detect sound. If the test shows movement when you speak, the microphone is probably working at the browser level.

This layered approach keeps troubleshooting sane. Instead of changing every setting at once, you learn where the signal stops. The goal is to answer one practical question quickly: can this microphone capture my voice right now?
