OK, I ran a check on the audio file, and the only thing I could deduce is that for some reason, the file copyrighted. Yeah, I know. WTF?
I'm gonna have to work around this somehow, because there were a few other non-DOA related audio files that I was told weren't working because of a similar issue today. If this doesn't work on MEGA, I'll have to make this a full video instead.
