Sound issues with missiles.

i have a missile launch sound i am trying to get to play when the missiles fire on my character. my machine gun noise works fine. the music in the level work just fine. the few explosions i have all work just fine. but when the missiles fire it is the awful noise that is just some electronic garble. if i set my machine gun to make the same missile sound it works just fine. not when it is attached to missile itself. i’ve played around with it as much as i can and all i can do is scratch my head.
