Microphone not working? Follow the signal.

Start the microphone test. A moving meter means this browser received a signal, but your meeting app may select a different input.

Access blocked?

Check both site and operating-system permissions using the permission guide. Denied access does not establish broken hardware.

Meter stays still?

1. Check a hardware mute switch and headset boom position.
2. Select another input. Bluetooth headsets can expose several endpoints.
3. Check system input level and the selected microphone.
4. Record a short local sample and listen back.
5. Compare another cable, port or microphone, changing one variable at a time.

Works here but not in a meeting?

Select the same microphone in the meeting app. Check its mute and permission state, then rejoin if the input does not refresh. An app mismatch is a likely configuration issue.

Distortion or cutouts?

Lower gain when peaks repeatedly approach full scale. Move closer rather than boosting gain excessively. Compare noise suppression settings and a wired connection where available. Then check speakers and camera.
