A plug-in could be used to override the HAL's handling of that
property. The property in question is
kAudioDevicePropertyPreferredChannelLayout.

I saw that in the AudioMIDISetup Utility in 10.3 you can set the
AudioChannelLayout of a hardware device. Will my kernel driver get
notification of such changes? If so, how? Is there updated
documentaion for audio drivers in 10.3? Will that break
compatibility with 10.2?
No,
This (at this stage) is so clients know how to channelise the data
depending on how the user has plugged in their speakers.
Would it be possible to pass that property through to the driver with
an AudioDriverPlugin? Or can the AudioDriverPlugin only pass
properties that it created itself?
