Microphone Not Working

A microphone that does not work is usually blocked by a privacy setting, not broken. Open the mic test first: if the meter moves there, the mic works and the problem is in a specific app.

Allow microphone access

Browser: click the padlock/tune icon in the address bar → Microphone → Allow, then reload. Windows: Settings → Privacy & security → Microphone → enable access, app access and desktop apps. macOS: System Settings → Privacy & Security → Microphone → enable the app. Android/iOS: Settings → Apps → the app → Permissions → Microphone.

Pick the correct input

Windows: Settings → System → Sound → Input. macOS: Sound → Input. Webcams, headsets and virtual devices all appear as microphones; choose the one you are speaking into.

Check the hardware mute

Headsets often have an inline mute switch or a mute button on the earcup that lights red. Some laptops have an F-key with a crossed-out mic.

Levels and boost

Set input volume to 70–90 %. If the meter barely moves, add a little boost (Windows: Sound Control Panel → Recording → Properties → Levels). Our microphone settings guide covers every Windows version, macOS and Linux.

Connectors

A 4-pole headset plug (TRRS) needs a combined jack; PCs with separate pink mic and green headphone jacks need a splitter. USB mics should be plugged directly, not via an unpowered hub.

Close apps holding the mic

Some apps take exclusive control. Quit Zoom, Teams, Discord, OBS and recorders, then retest. Disable exclusive mode in the mic’s Advanced properties on Windows.

Drivers

In Device Manager → Audio inputs and outputs, update or reinstall the mic driver. For USB mics, try another port and cable.

App-specific fixes

See Discord mic not working and Zoom camera and mic fixes. Record yourself with the voice recorder to judge quality.
