The Core will be responsible for providing the audio, i.e. audio 
transport, accessing the sound devices (speaker, microphone), codecs and 
so on. So if the user wants to change the volume, the Core has to be 
notified and has to perform the change.

If another application is changing the volumes, or if the user does this 
manually, the Core has to notify the GUI that the volumes have been 
adjusted.

I hope the issue is somewhat clearer now.
