Callback for kAudioDevicePropertyDeviceIsRunningSomewhere changes

Subject: Callback for kAudioDevicePropertyDeviceIsRunningSomewhere changes

Hello,

I am able to use AudioDeviceGetProperty() and
kAudioDevicePropertyDeviceIsRunningSomewhere to determine if someone is
using my AudioDevice. However, if I register for a callback for changes
to this property I am never called.

I also tried running "displayhaldeviceinfo -notifications" and didn't see
a notification there either. :(

Is this a known limitation/bug? I'd rather not poll
AudioDeviceGetProperty()...

Thanks!
