How to fix a microphone not working in a browser
Step-by-step fixes for permission, device, and no-signal problems.
Common causes and fixes
- Permission denied: click the padlock in the address bar and allow the microphone, then reload.
- No device found: connect or enable your microphone, then retry.
- Signal stays at zero: choose the right input device, and unmute it in your OS.
- Device busy: another app is using it — close that app.
