Sound tab enhancement

I think I have the correct category/label, right? I have an idea that when a tab plays sound and we have more than our allotted tabs set the parent tab indicator above the tabs should flash or do something when sound is playing from a tab within the parent group. I probably didn’t describe this as good as I could have but its as good as I could.

With the switch off of muon, we now display a speaker icon for tabs which are playing sound. I believe it is safe to close this issue.
