As I was the one that posted the above wiki, I tested disabling the audio looping by deleting the 'storedaudio' section of that code and recompiling. It seems to work as expected, audio and playlists no longer loop. No adverse effects seem to be appearing.There may be a simpler way that I'm not familiar with.
