It really doesn't seem like sound playback is there yet, except in Flash.
look more into the apis i referenced. not only is javascript playback there, but even the synthesis is possible through javascript.

It creates a flash object on the fly with javascript:
<object id="guitar11-sound-player" width="0" height="0"
type="application/x-shockwave-flash"
codebase="http://download.macromedia.com/pub/shockwave
/cabs/flash/swflash.cab#version=9,0,0,0"
classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000">
too bad they didn't synthesize the sound with javascript as well. their web audio api is great. firefox has a (somewhat) equivalent api. :)
