Zoom Randomly Taking Over Screen

[4YTfun07]

I will be in my college zoom call and when I'm not busy after my assignment is done i might watch YouTube or research something else, but the zoom call will randomly overtake my web browser. This has been happening for months and i think i finally found out why. My instructors microphone is loud so i keep my volume down but when i watch a video after he is done talking its too quite so i will turn it up and then it takes over. When it takes over i see a pop up that says something like "trouble hearing? Turn up Volume." and i think that popup is what causes it to reappear
