What properties need to be set to make it happy? I imagine that once
it's configured it probably behaves in a similar manner to the
DefaultOutputUnit?
For me, it did. The main important property is
kAudioOutputUnitProperty_CurrentDevice, which you set to a
AudioDeviceID of your choice. Use the functions defined in
AudioHardware.h to query available hardware and its capabilities.
I think the DefaultOutputUnit does some fancy footwork to convert the
canonical format to the device format - would a HALOutputUnit do this
by default or would we have to connect it to an Converter before wiring
it into a graph for example?
It's basically the same as DefaultOutputUnit, except that you can set
the AudioDevice it should use.
