On the Intel iMac, there are two input devices (one analog and one
digital) and one output device. All three devices are clocked
independently and, much like USB devices, are represented as three
separate devices in the HAL. This presents something of a new
situation as there are no bi-directional devices on the system by
default anymore. Code needs to be able to deal with that situation.
That said, I don't know a whole lot about MTCoreAudio, so I can't say
if it can handle that situation. I do know that it's pretty hard to
get into a situation on these systems where the HAL won't return a
default input device.

I've created a simple project on my PPC using MTCoreAudio and it

I can't even get Recordotron nor the sample "AudioMonitor" provided
with MTCoreAudio to work on my iMac. With AudioMonitor I get an
error "Zerolink: unknown symbol
_MTCoreAudioHardwareDeviceListDidChangeNotification". If I change
to "deployment" then I get a long list of undefined symbols.
