How to Troubleshoot Common Teams Audio & Video Issues

Diagnosing and fixing issues when participants can’t hear you, you can’t hear them, or your camera won’t turn on.

 Instructions

1. Before You Start

   • Close any other apps that might be using your microphone or camera (e.g., Zoom, Skype).

2. Check Device Settings in Teams

   1. In a meeting (or call), click Devices (gear icon next to mic) in the toolbar.

   2. Under Audio devices, verify the correct Microphone, Speaker, and Camera are selected.

   3. Test mic/speaker: click Make a test call (desktop) to record a short message and ensure playback works.

3. Adjust OS-Level Permissions

   • Windows 10/11:

     1. Go to Settings → Privacy & security → Microphone / Camera.

     2. Ensure Allow apps to access your microphone / camera is On.

     3. Scroll down and verify Microsoft Teams is allowed.

   • macOS:

     1. Go to System Preferences → Security & Privacy → Privacy tab.

     2. Select Microphone and Camera on the left.

     3. Ensure Microsoft Teams is checked in both.

4. Test with another App or Device

   • Open a different conferencing app (e.g., Skype) to see if the hardware is detected.

   • If that fails, try plugging in a USB headset or external webcam and reselect in Teams.

5. Network & Bandwidth Checks

   • If on Wi-Fi, try switching to a wired connection or moving closer to the access point.

   • Ask other participants if they hear/video you; if not, the issue might be on your end.
