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. If the browser test works but the meeting app does not, focus on the app settings. Check the selected input device, mute status, permission prompts, and whether another app is using the microphone. If the browser test does not detect sound, move outward. Check the physical mute switch, cable connection, Bluetooth battery, operating system input settings, and privacy permissions. This layered approach keeps troubleshooting sane.
