How about: (defun play-sound (sound &optional async) ...

With the ASYNC parameter being:

- nil, block while playing (backward compatible).
- t, play the sound asynchronously.
- A callback function which is executed once the sound playing 
 process terminates.
 I'm not familiar enough with the play-sound API to say whether 
 or not it'd be useful to pass something back to the callback 
 function.
