Microsoft Teams comes with Skype integration, which allows users to make calls via Skype Business. However, some users have reported that Microsoft Teams does not recognize the microphone in the desktop client.

This problem can occur for several reasons, one of which is software bugs. It can also occur if authorization issues prevent access to your microphone.

Make sure that Teams have permission to use the microphone.

  • You can go to System Preferences > Security and Privacy > under the Privacy tab > Microphone.
  • Check to see if the teams have authorization.

Check Hardware Connections

The first step is to check whether your microphone has a faulty hardware connection. This is fairly easy to do. First disconnect your microphone, then reconnect it. You should hear a sound indicating that Windows has detected new hardware.

You don’t have any sound messages? Open the Start menu and search for “Device Manager. Click the first option that appears.

Then click to expand the Audio Inputs and Outputs section of the Device Manager. If your microphone is plugged in, it should appear here.

If you do not see your microphone here, unplug and plug it back in.
