What Am I Using?
Microphone not working?
Test the microphone in a second app. Check mute controls, device selection, system permissions and site permissions before your next call.
Does the microphone work in another app or test?
Use a built-in recorder or the microphone checker. Start the check yourself and speak a short sample.
Device and operating system
Choose the right microphone in the affected app
A successful local test suggests the microphone can capture sound. Each meeting app or website can still select or block its own input.
- Open audio settings in the affected app. Select the microphone by name and watch its level meter.
- Check the headset mute button and the affected website’s microphone permission. Rejoin or reload once after changing it.
Check the device’s input and permission
The operating system can block access or use a different microphone as its input.
- Reconnect the microphone or headset and check any physical mute switch.
- Allow access for the intended app, then choose the microphone as the system input if your device offers that setting.
- Record a short sample. If the built-in microphone works and the external one does not, test the accessory with a known working port.
Check which permission prompt is blocked
A permission message can name the app, browser or system setting that needs attention.
- Look for the browser’s permission indicator and any system message.
- If the device is managed or the permission is locked, give the exact message to IT.
