OK something even weirder is it has something to do with the files, not the code. If I change all the code to play the one sound that's working, I don't get this issue. Even if the only thing I change is the reference to the sound. I'll attach one of the sounds I'm using that causes the problem. Is there anything wrong with this sound?
