Browser extension that shows you which tabs aren’t muted

Infinite tabs of YouTube auto-playing ads seem to be becoming worse and worse recently. Would be nice to have some way of finding them. I can’t imagine there’s 100% no method of figuring out which tabs are making noise, every browser data dashboard shows it. <br><br>I used this idea on a personal admissions interview this morning successfully, although the interviewer did say he believed there is already an extension like this but I haven’t found one.
