It is already known that sounds with PlayOnRemove set to true play when you close the game. It is perhaps lesser known that this happens regardless of whether the user has their volume set to 0 on the client. I have it set to 0 quite frequently, and the result is that sometimes I hear audio when I don’t expect to.
Find The Doge Heads 2 provides a good way to test this behaviour. For whatever reason (I believe unintentional), there is a glass breaking audio in the game that briefly plays when you leave.
Expected behavior
I expect to not hear the sound play at all, since my volume is at 0.
