  12     This class represents a short sound (loaded from Windows WAV file), that
  13     can be stored in memory and played.
  14
  15     Currently this class is implemented on Windows and Unix (and uses either
  16     Open Sound System or Simple DirectMedia Layer).

  75         after calling this function and the sound would continue playing, however this
  76         currently doesn't work under Windows for sound objects loaded from memory data.
  77
  78         The possible values for @a flags are:
  79         - wxSOUND_SYNC: @c Play will block and wait until the sound is replayed.
  80         - wxSOUND_ASYNC: Sound is played asynchronously, @c Play returns immediately.
  81         - wxSOUND_ASYNC|wxSOUND_LOOP: Sound is played asynchronously and loops
  82                                       until another sound is played, Stop() is
  83                                       called or the program terminates.
