Quick fixes

  • Pick the correct audio device in Teams settings
  • Reconnect headset or pick it inside the meeting
  • Check microphone permission in the OS

Microphone not detected

In Teams: profile picture top right, Settings, Devices. Confirm the correct microphone is selected. Teams sometimes picks the wrong default after an update.

Microphone permission in the OS

Windows

  1. Settings, Privacy and Security, Microphone
  2. Enable “Let apps access your microphone”
  3. Enable Microsoft Teams in the list

Direct link: ms-settings:privacy-microphone

macOS

  1. System Settings, Privacy and Security, Microphone
  2. Enable Microsoft Teams
  3. Quit Teams and relaunch - permissions are evaluated only on launch

Linux

On modern distros with PipeWire:

pavucontrol

Open, “Recording” tab, show Teams as a running source, pick the correct input.

On Wayland, ensure xdg-desktop-portal and pipewire-pulse are installed.

iOS

  1. Settings, Privacy & Security, Microphone
  2. Enable Microsoft Teams

Android

  1. Settings, Apps, Microsoft Teams, Permissions
  2. Allow Microphone

No sound from the speakers

Make sure the correct output device is active. A connected monitor with its own speakers can hijack playback.

Windows

Click the speaker icon in the taskbar, the arrow up for selection, pick the device.

macOS

Hold Option and click the speaker icon in the menu bar - you can pick input and output directly there.

Echo or feedback

Enable echo cancellation in Teams Settings, Devices. When possible use a headset rather than separate speakers and microphone.
