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