Theme sound mask constants define masks that are used to specify the classes of sounds that are enabled for a theme. You can use these masks to operate upon the unsigned 32-bit integer contained in the kThemeSoundMaskTag collection item, which is described in Theme Collection Tags . Theme sound mask constants are available with Appearance Manager 1.1 and later.
