    1.31 + *  An interface to Global Audio Settings observer callback functions.
    1.32 + *
    1.33 + *  This serves as the method of communication between the client and the
    1.34 + *  CGlobalAudioSettings object.
    1.35 + *
    1.36 + *  The class is a mixin and is intended to be inherited by the client class
    1.37 + *  that is interested in observing the global audio settings. The functions
    1.38 + *  encapsulated by this class are called when events occur which causes device
    1.39 + *  audio settings to be changed that affects the overall audio behavior.
