The way it works at this point is that a sound file is tied to a sound 
source. And you can't change the file associated with a source afterwards.

So to play multiple files one after another you need to create a new 
source and stop, and remove the other one.

I don't know how that would work using Nasal though, I'm unfamiliar with 
that part of the sound code.
