There was some format forcing in my audio session configuration (I

kAudioFormatFlagIsNonInterleaved added to the format flags. See
below for the extracted section. Further recommendations?
I also realized after reading through more of the list that I may
not need a varispeed unit at all. I extracted that from the graph
over the weekend (i.e. only using the Output unit) - though I'm
still not getting any audible output despite all assertions
passing. Which leads to another question..
Can you confirm whether or not the output units have configurable
output buffer size? For instance, I'd like to feed 22K worth of
audio in a buffer, and the AU wants it 4K at a time,
so you have to provide 4K of data at a time.
