๐Ÿ› ๏ธ How to Troubleshoot a Silent Microphone

  • Check Browser Permissions: Look for the lock or camera/mic icon on the left of your address bar and ensure "Microphone" is set to "Allow".
  • Operating System Privacy Settings: In Windows 11/10 (Settings โ†’ Privacy & Security โ†’ Microphone) or macOS (System Settings โ†’ Privacy & Security โ†’ Microphone), verify browser access is enabled.
  • Hardware Mute Switch: Many headsets have an inline physical mute toggle or a flip-up boom mic that mechanically mutes audio.
