How to Stop audio from playing (Play Sound at Location)

DG Gage - I was having the same problem, then I came across this question, and it helped a lot. However I have one question if you don’t mind me asking, How do I make it so it doesn’t play the sound when I’m not in the box trigger? I am very far away from it in the game, and it will still play the sound. If I go into it however, it will fade in, and when I go out, it fades out, THEN the sound stops. How do I fix that, and what is it that’s doing that?
