This is a hack to get around the fact that the SM does not support anything
more than 2 channels and has been a burden for many developers on Mac for
many years...
Now for the good news... You don't have to do this anymore, because
CoreAudio gives you more than 2 channels.
If you look through the example in:
/Developer/Examples/CoreAudio/Services/DefaultOutput
You'll see a good example that is pretty simple for using the output unit
with the audio converter, so that the code is very similar to using a SM
sound channel with buffer and callback cmds...
