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