Audio tracks in certain scenes will fail to play. This seems to be an intermitent issue and seems to happen without an identifiable cause. If I cancel out of the project and go back into it, the file in question will play. However, after further editing of the project, other audio files might refuse to play. Then you'll have to repeat the process of backing out of the project and loading it again.
It is difficult to describe a workflow that will faithfully reproduce the bug. Suffice it to say that it happens a lot. The audio tracks I'm using are MP3 audio files with standard encoding.
