The output buffers are there for _you_ to put data in. Until you do
that, the buffers will be filled with zeroes.
The system does not provide any means for accessing the output data
going to the device.

Hi, I have set up a little callback to get the samples from the
default device. I just copy the input and output into global
buffers and then draw those on a gworld with SetCPixel(). Anyway, I
can see my voice when I speak, but I have tried everything and can't
seem to capture the mac's sound output. Does anyone know of code to
get the output as an input? Is it supported by the OS?
FYI I am using this for echo cancellation. Ideally I'd like to get
the Mac's entire sound output, but just the output of the app is
fine too.
