Make a Test Call
To make a test call, select your profile picture at the top of Microsoft Teams,
then Settings > Devices.
Choose Make a test call under Audio devices.
In a test call, you'll see how your mic, speaker, and camera are working. Follow the instructions from Test Call Bot and record a short message. The message will play back for you. After that, you'll get a summary of the test call, and you can go to your device settings to make changes.
The test call feature is only available in English for now. Additional languages are coming soon.
We'll delete your test recording immediately after the call. It won't be retained or used by Microsoft.
Change your default mic, speaker or camera
To select the mic, speaker, and camera you want Teams to use for calls and meetings, click your profile picture at the top of Teams, then Settings > Devices.
Under Audio devices, pick the speaker and mic you want Teams to use by default.
Under Camera, select the camera you want Teams to use, and see a preview of that camera's video.
