FIX: Microsoft Teams Microphone Not Working Problem

Everything you need to know about fixing microphone issues in Microsoft Teams

Unfortunately, the sudden increase in user base also resulted in enormous pressure on the underlying infrastructure of the software. And if that wasn’t enough, the Teams desktop app is kind of a drag too when it comes to things as basic as video calling.

Many users have reported issues like camera not working in Teams and microphone issues where the software wouldn’t detect the Mic at all. Thankfully, these problems are fixable on the user level in many ways. Read on to find some of the most helpful tips to fix microphone issues in Teams below.

On the sound settings screen, click on the ‘Manage Sound Devices’ link to see a list of all sound devices on your computer.
