I have just one followup question on this topic:
How do I identify which device is the built-in audio Apple hardware?
There don't appear to be any methods that would tell me that a
particular piece of hardware is the built-in hardware. By the way, I'm
looking at this page here as it seems most relevant to what I'm doing:

Is there somewhere else I need to look? Is there sample code that
might help?
TIA
Examine the device's Transport Type.
Thanks for the reply. I'll look into this later, but I guess I found one
of those occasional documentation bugs:
"kAudioDevicePropertyTransportType
A UInt32 whose value indicates how the AudioDevice is connected to
the CPU. Constants for some of the values for this property can be found
in ."
I guess I can find the constants for the property somewhere in one of
the header files.
