There really isn't a mechanism on Mac OS X that works like you are used to with wave out on Windows.

At any rate, for basic playback, you should check out the sample code in /Developer/Examples/CoreAudio/SimpleSDK/DefaultOutputUnit

I need to play pcm buffers asynchronously.
I've spent way too much time looking for how to do this on my own. I could use some help.
Our data will be 11k 8-bit mono.
On windows (for reference), we're doing this with waveOutPrepareHeader() and waveOutWrite().
There's a callback we get when the buffer is played.
We need a similar mechanism for the mac.
