Ok for those of us who need a simple answer to the question of how to Stop a Song or Audio with out all the techy issues that keep coming up. Like Varibles, Functions and all that mess.
Here it is in the simplest way. When playing sound set "TAG" To what ever you want in that event. Then on action like kill enemy or button press Use the "TAG" you set in the play clip event. to stop, pause, resume and what ever else you want to do with it.
Have fun and enjoy.
