Platform: Browser, Desktop & Mobile Apps
If you are experiencing issues with audio or video in Microsoft Teams when conducting online meetings, use the following tips to troubleshoot:
Use the Teams app
If you are using the Teams web app, it is recommended you use the desktop/mobile app instead for the best experience. You can download the Teams desktop app here.
Set or change your default microphone, speaker, or camera
To set or change your default input devices in the Teams desktop application, follow the instructions below:
- To select the microphone, 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.
During a meeting
To change your speaker, microphone, or camera settings when you’re on a call or in a meeting, select More options > Show device settings in your meeting controls. Then, select the speaker, microphone, and camera options you want.
Make a test call
You can conduct a test call within Teams to ensure your audio & video settings are correct prior to joining a meeting:
- Select your profile picture in the top-right, 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.
Virtual backgrounds unavailable
Virtual backgrounds in Teams are only available on the desktop and mobile applications. Additionally, this option may be unavailable to you if virtual backgrounds are not supported on the device you are using, which can be a result of limited system resources.
Limited network or system resources
If you are experiencing intermittent audio or video connectivity, its possible your network connection or system resources are the cause. Check your internet connection speed to ensure it is fast enough for streaming video, and also close out of any unnecessary programs to free up additional system resources.
