Vlad Safari doesn't offer a 'Mute Other Tab' option in tab context menus (which makes sense to me), instead only including it in the menu bar under Window, same as Orion. In the menu bar it does correctly enable "Mute Other Tabs" if other tab(s) are playing audio regardless of whether the current one is or not:
No other tabs playing (both when the current tab is and isn't playing audio):
One other tab playing audio when the current tab is not:
Multiple other tabs playing audio when the current tab is not:
(A little pluralisation inconsistency on their end that is not a big deal at all: if the current tab and one other tab are playing audio the menu item still reads "Mute Other Tabs" when it should be "Mute Other Tab" – looks like they're counting the current tab in the pluralisation total.)
