Step-by-step fix

  1. First, confirm the mic itself works: run the CheckMyMic microphone test.
  2. In Discord, open User Settings → Voice & Video → Input Device and select the correct input device.
  3. Check the input level and make sure you're not muted inside Discord.
  4. Grant Discord microphone permission at the operating-system level.
  5. Restart Discord and rejoin your call.

Frequently asked questions

My mic works in the browser test but not in Discord — why?

That points to Discord's own device settings. Open User Settings → Voice & Video → Input Device and pick the same microphone that worked in the test.

Does Discord need separate mic permission?

Yes — even if your browser or system has access, Discord may need its own grant. Allow it in your OS privacy settings, then restart Discord.
