I think that you can use QTKit to load and play sound files

QuickTime is pretty non-thread-safe too.
And there we're using the definition as "non-thread-safe"=="requires
the main thread" :). QTMovie on 10.5 has +enterQTKitOnThread/
exitQTKitOnThread, but I saw regular crashes on secondary threads due
to certain codecs trying to display an app-modal panel.
NSSound already plays the sound asynchronously. It's apparently
loading the sound that blocks for a long time (although it's lazy
enough that it won't actually load the sound till the first time you
ask it to play). I'm not sure QT would do any better (especially
since NSSound may well be using QT under the hood anyway.)
Or maybe the _initializeCA is setting up CoreAudio? Wild guess...I've
never used CoreAudio.
