Okay, so, I disabled that, and it fixed my title screen sounds. Ingame sounds like blasts and explosions still don't appear to be working. They either play halfway and get cut off, play all the way through, or don't play at all. I removed all instances of "mute audio" in my event pages, but it doesn't seem to fix the issues.
Here's an updated capx with the sounds so you could test it yourself and see what I am talking about.

Please help, I plan to have this fixed when Ludum Dare judging is over, but I really would like to get it out of the way.
