This is precisely what the HAL property,
kAudioDevicePropertyRelatedDevices, is for:
@constant kAudioDevicePropertyRelatedDevices
An array of AudioDeviceIDs for devices
related to the AudioDevice. For
IOAudio-based devices, a AudioDevices are
related if they share the same
IOAudioDevice object.

I saw Logic Pro 7.2 shows those built-in devices as "Built-In Mic"
and "Built-In
Line" only. "Built-In Output" is automatically combined with both
of those two
input sources. I'd like to do the same thing in my application.
Are there any information like "This input should be combined with
that output"?
Or, we have to write special code for that, I mean that I have to know
"Built-In Mic and Built-In Line should be combined with Built-In
Output"?
