I am using this small function to give me sound support on OSX:
https://raw.github.com/leoliu/play-sound-osx/master/play-sound.el

Two conscious abuses (can be fixed):

 - misuse (signal 'wrong-type-argument (list sound)); it requires the
   first item of DATA to be a predicate but I decided not to add another
   function.

 - async; should probably use call-process to stay close to the C
   version.

BTW, I only remember once in the past years needing the feature.
