[racket] play-sound

Sound isn't really the forté of windowing applications. I'm not sure why
"play-sound" is in there at all. But to be more helpful, do you have
"portaudio" support? You could try using the planet package for that:

(require (planet clements/rsound:1))

I haven't tried it yet. Can supposedly play 16-bit PCM though!
