OneShotPlayer fails with some .wav files

With certain .wav files module OneShotPlayer outputs buzzing noise regardless of if the play has been triggered or not.

To reproduce:
- add bell_clip.wav to AWE Designer /Audio.
- open test_one_shot_player.awd and run.

Note, bell_clip.wav is just a segment of existing bell.wav in /Audio.

Other questions:
1. Is there a minimum length of the .wav file for the player to work correctly?
2. When is the file accessed and added to the layout? Is it every time the layout is run or only when the .wav path/filename is changed?

Thanks,
James
