Fix a microphone that is not working in Zoom on Windows
Source-checked About 10 minutes
Answer
Select and test the correct microphone in Zoom, allow desktop-app microphone access in Windows, then reconnect or update the audio device.
Check the starting state
Before changing a Zoom microphone, select the exact microphone, note whether Windows and another app can record it, and record Zoom's input level and current meeting-device choice. Keep the current state, exact message, and any recent change available so each result can be compared.
Choose the supported path
Distinguish an incorrect Zoom device, muted hardware, Windows desktop-app permission, Bluetooth call profile, and a microphone that fails system-wide.
Test the microphone in Zoom
In Zoom, open Settings > Audio, select the intended microphone, and run Test microphone. Watch the input meter and listen to the playback.
Check the meeting control
Join audio and make sure the microphone button is not muted. Use the arrow beside it to select the same microphone.
Allow microphone access
In Windows privacy settings, enable microphone access and allow desktop apps to use the microphone.

Reconnect and update
Reconnect USB or Bluetooth hardware, restart Zoom, and install the official audio driver or Windows update if the device is missing.
Verify the result
Zoom's Test Mic playback is clear and a private test meeting uses the same input after reconnecting the device. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
Troubleshoot a Zoom microphone
If the Windows input meter never moves, only Zoom remains silent, Bluetooth exposes the wrong profile, or organization policy controls microphone access, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
