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.
Just FTA, my DTK-replacement iMac Core Duo reports these Intel HD
Audio devices as:
Built-in Mic (2-ch stereo, L = R)
Built-in Line In
Built-in Output
Streams are mixable, 16-bit LE signed int and 20/24-bit LE signed int
aligned low in 32. Buffer size ranges are each 14-3072 frames.
