5 fixes for Microsoft Teams microphone not working on Windows 10

More businesses and organizations now use Microsoft Teams to manage their teams working from their office or remotely. The app has a handful of features you might need in a video / web conferencing tool. However, like all other tools, Microsoft Teams also has its shortcomings. During a video or voice call, for example, you may encounter an error message “Your microphone is not working”. In this guide, we present 5 different fixes to the Microsoft team microphone problem.

This error message appears when Microsoft Teams cannot recognize the microphone on your computer or headset. Some anomalies with your Windows microphone settings or audio driver (s) could also cause this error.

Other times, the Microsoft Teams application spoils. Let’s move on to the solutions.

1. Restart Microsoft teams

2. Connect the audio device before the call

For some reason, the Teams app sometimes doesn’t recognize your audio device’s microphone if you plug it in during a call. This could be due to a bug with the Microsoft Teams app.
