AudioObjectPropertyAddress confusion

Subject: AudioObjectPropertyAddress confusion

Hi,

I'm changing some of my code to use AudioObjectSetPropertyData / AudioObjectGetPropertyData. However, I'm still confused about AudioObjectPropertyAddress; the meaning of mSelector is clear, but I still don't understand the scope and element fields. The documentation lists the possible values, but doesn't really explain when or how they are used. For example, if I want to change the sampling rate of my device (i.e. kAudioDevicePropertyNominalSampleRate), which scope and element am I supposed to indicate?

Thanks,

Alex
