Hello everyone !
I have had this issue for about 3 weeks now. It started pretty much out of nowhere. I am on a Macbook Pro M1.
From time to time, I have a shadow popup stating that it has detected a new microphone named “Microsoft Teams Audio” :

I don’t have microphones activated in Shadow and never had this popup in more than a year using Shadow. It is not that bothering since I mostly play solo games (Doing The Witcher series right now) but it can be upsetting since it can happen 2 or 3 times in a 3 minutes window. It is pretty rare though. Most of the time it happens once every hours.
I tried uninstalling microsoft teams from my computer but I still have the popup.
Does someone have an idea of what it can be ?
