Yeah, it just looks like a simple bug arising from no test having been 
done with no slots. My hack to start at 2 has got me to the point where 
my demo runs and plays the expected WAV file. It then gets a 
segmentation fault on an alSourcef call, which I will look at tomorrow.

Rayiner, did you get my note about the missing in-package form?
