Applies to: Microsoft Teams
Last updated: September 18, 2026
- Before the meeting, open Teams settings > Devices and choose the speaker and microphone you mean to use. Speak and watch the level move.
- If the level stays flat, open Windows Settings > Privacy & security > Microphone and allow microphone access, including for desktop apps.
- In the meeting, select the arrow next to the microphone and pick the device again. Bluetooth headsets sometimes reconnect as a second device.
- Quit other apps that might hold the microphone, then rejoin the call.
