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.
Does this mean that we'll need to use an aggregate device to
"combine" input and output to solve the clock sync issues when doing
full-duplex audio?
Thanks
