There are multiple reasons that might also be prompting your Microphone in order to misbehave on a team’s call. Firstly, you have to make sure that the Microphone is functional. To do this, just connect the Microphone to another device (your mobile phone works as well) and try calling someone. If they are able to hear you loud and clear, the Microphone does also works, and you guys can rest assured of no new expenses. You can also try using any other application that needs input from the Microphone. Such as Discord or a different video calling program, and then check if it works there.

Also, did you try simply restarting the application as well as plugging the Microphone out and back in again? We know you did, however, it doesn’t really hurt to confirm. PC users may also try plugging the Microphone into another port (the one present on the CPU). If there is actually a mute button on the Microphone.

Many times, Teams may also fail to detect your Microphone if you guys connect it while in the middle of a call. In order to connect the Microphone first and then place or join a call.

  • Then hop over to the Permission page.
  • There, just check if the application is allow access to your media devices (Camera, Microphone, and speaker). Tap on the toggle switch to enable access.
