Have you ever tried to join a Teams meeting when you are in a room already connected to your meeting so you can share content? If so, you may have noticed that this causes an infinite feedback loop, which results in an echo, and in most cases the echo quickly turns into a howl (like when a musician holds his microphone close to a speaker) .
Soon, ifmultiple users are connecting from the same location, your Teams client will tell you that another Teams device is detected nearby and is already attached with audio to the current meeting. The Microsoft Teams client will then automatically mute your microphone and speakers on your Windows or Mac OS laptop.
