Fix Zoom ‘Failed to Detect Microphone’ in Windows 11
Source-checked About 10 minutes
Answer
Reconnect and unmute the microphone, select and test it in Zoom Audio settings, allow desktop-app microphone access in Windows, and update the audio driver if the device is absent.
Identify and test the exact audio device
Confirm the exact microphone, headphones, port or wireless connection, then record the selected Windows input and output, volume, mute state, app permission, and result in another trusted recording or playback app. Keep gain low while testing to protect hearing and avoid feedback. Change one mixer, enhancement, format, permission, or driver setting at a time.
Reconnect the microphone
Insert a wired microphone fully into the correct port. For a Bluetooth microphone, confirm it is powered on and connected. Check its hardware mute switch, then fully quit other apps that may be using it.
Select and test the microphone in Zoom
In Zoom, open Settings > Audio, select the microphone, start the test, and play back the sample.
Allow desktop microphone access
Open Windows Settings > Privacy & security > Microphone. Turn on Microphone access and Let desktop apps access your microphone, then reopen Zoom.
Check whether Windows detects the device
Test the microphone in Windows Sound settings or a trusted recording app. If Windows cannot detect it either, troubleshoot the connection or device driver before changing more Zoom settings.
Run Zoom's microphone test again
Return to Zoom Settings > Audio, select the intended microphone, and run the microphone test. Play back the sample before joining a meeting.

If it does not work
- If Zoom still detects no microphone, confirm the device in Zoom's test, Windows input settings, privacy permission, hardware mute and another recording app. Close competing audio apps and use the device maker's exact driver only when Windows also fails to record.
