All of the things you mention might change.

Internally, the HAL will only hand out these notifications while the IO thread is blocked. This means that you can be sure that your IOProc won't be called while you are doing whatever you deem necessary for the kAudioDevicePropertyStreamConfiguration notification.

Please can someone help with this newb question :

In AudioHardware.h, it states that the kAudioDevicePropertyStreamConfiguration notification
should be listened for. If the IOProc and device have started, do changes to the stream
configuration affect the IOProc ? If so, what properties of the config can change and how
should this be handled?

Properties that might be able to change :

Number of buffers (AudioBufferList)
Number of channels (AudioBuffer)
Buffer sizes (AudioBuffer)
