Step-by-step fix
- First, confirm the mic itself works: run the CheckMyMic microphone test.
- In Zoom, open Settings → Audio → Microphone and select the correct input device.
- Check the input level and make sure you're not muted inside Zoom.
- Grant Zoom microphone permission at the operating-system level.
- Restart Zoom and rejoin your call.
Frequently asked questions
My mic works in the browser test but not in Zoom — why?
That points to Zoom's own device settings. Open Settings → Audio → Microphone and pick the same microphone that worked in the test.
Does Zoom need separate mic permission?
Yes — even if your browser or system has access, Zoom may need its own grant. Allow it in your OS privacy settings, then restart Zoom.
