I can successfully create an aggregate device with kAudioPlugInCreateAggregateDevice. I can successfully add subdevices to the aggregate device with kAudioAggregateDevicePropertyFullSubDeviceList. I can successfully set one of the subdevices as the master clock with kAudioAggregateDevicePropertyMasterSubDevice. I can successfully get the objectIDs of the subdevices with kAudioObjectPropertyOwnedObjects. However, I am unable to set kAudioSubDevicePropertyDriftCompensation for any of the subdevices using AudioObjectSetPropertyData(). I've tried at least a dozen different combinations of parameters for the function, but I always get kAudioHardwareUnknownPropertyError. Does anyone know the magic combination to get this to work? FWIW, I'm running Mac OS X 10.8.5.
