Sound won't play in half my scenes?

I'm making a simple "Choose Your Own Adventure" style thing. It's quite small, only about 12 branching choices. Once I get about halfway in, the audio won't play on one of the scenes, and all subsequent scenes. I've tried updating the audio files, nothing. I can't see how it could be code related because I have all of my audio files set to sync and I just have buttons that move from to the first frame in each scene (gotoAndPlay). Any thoughts?

Also, the audio works just fine when I test each scene individually. It's just that half of the scenes don't work when I run the full movie.
