{-
  Note to self: I need to terminateAudio for the purpose of stopping sound
  from Audible objects before they vanish (e.g., before a level change).
  However, I am also concerned about the fact that the Sound.OpenAL API
  doesn't seem to have any call for destroying a Source. I wonder if this is
  handled automatically somehow, if I this will lead to a memory leak, with
  Source objects accumulating in whatever system stores them.
