    This class represents a short sound (loaded from Windows WAV file), that
    can be stored in memory and played. Currently this class is implemented
    on Windows and Unix (and uses either
    Open Sound System or
    Simple DirectMedia Layer).

        possible
        to delete the object which is being asynchronously played any time after
        calling this function and the sound would continue playing, however this
        currently doesn't work under Windows for sound objects loaded from memory data.
        The possible values for @a flags are:
        
        wxSOUND_SYNC
        
        @c Play will block and wait until the sound is
        replayed.
        
        wxSOUND_ASYNC
        
        Sound is played asynchronously,
        @c Play returns immediately
        
        wxSOUND_ASYNC | wxSOUND_LOOP
        
        Sound is played asynchronously
        and loops until another sound is played,
        Stop() is called or the program terminates.
        
        The static form is shorthand for this code:
