Additional chat-related features and issues within Microsoft Teams for business
I solved the issue in my computer. I went to System > Sound > Volume Mixer and found that there were TWO Microsoft Teams Apps (probably because of an update?) in there and I just muted one of them. I tried the first one and realized that it really muted the Teams app but when I only muted the 2nd one it looked like it didn't do "anything" but fixed my sound. Now Teams is able to identify when I am talking vs before that it was thinking that my speakers was actually me talking.
