You need to use the HAL directly to examine the available devices. To
get you going, you'd use the system property,
kAudioHardwarePropertyDevices, to get the list of available devices.

Hi everyone:
I'm trying to get the list of connected audio output devices,
but I can only get:
Apple: AudioDeviceOutput
Apple: DefaultOutputUnit
Apple: GenericOutput
Apple: SystemOutputUnit
when what I really want to get is:
Built-in Audio
... [other audio devices]
just like AU Lab "Audio Device" menu when you ask for a new document.
I remember I had this options some time ago, but now, I reviewed
the complete list of components:
desc.componentFlags = 0;
desc.componentFlagsMask = 0;
desc.componentSubType = 0;
desc.componentManufacturer = 0;
This gives me a HUGE collection of components, but no one is "Built-
In Audio" nor "USB Audio Device".
Any suggestions?
