Microsoft Teams: Test your microphone before you join
From Microsoft's description: “Before joining a meeting on your pre-join screen, you can test your microphone and speaker to make sure others will hear you clearly.”
Before joining a meeting on your pre-join screen, you can test your microphone and speaker to make sure others will hear you clearly. Select Test mic and speaker to record a short audio clip and play it back. This helps you confirm that the right devices are selected and that you’ll be heard—and hear others—once the meeting starts.
