I have a sound in part of my map that won't turn on unless I set it to play everywhere, all other sounds work fine but its this one sound that won't turn on. I've tried triggering it too, and even though that same trigger turns everything else on, it won't turn THIS sound on. I even copied and pasted the sound's name into the trigger just to make sure, still didn't work.
So far the only way this fixes is if I set the "play everywhere" flag.
