Test video call audio before joining

A working headset does not guarantee that a meeting app has selected it. Run a short check in the app you will use.

1. Connect the headset and open the app's audio settings. Identify the microphone and speaker by name, especially when a monitor also offers an audio device.
2. Use an available test call or microphone preview. Say a normal sentence and listen to the playback; in desktop Teams, a test call can check your setup.
3. If sound fails, check the physical mute switch, volume and device selection. Review microphone permission for the app or browser before trying again.
4. Join early enough to make one correction. If you join from a second device, avoid enabling its microphone and speaker alongside the first.

Keep a fallback contact method in the meeting invitation. Test recordings should contain ordinary words, not confidential meeting details.
