This dialog is almost the same as the sound options dialog for objects. There is only one option which is not available in the object sound dialog: You can decide to stop all playing sounds and musics when the page is displayed or you can have them continue playing
If you choose the option "Stop all sounds" then all sounds will be stopped as soon as the page is displayed. All sounds and musics will also be removed from memory. If you choose the option "Continue sound", no action will take place and if you choose "Play sound", Hollywood Designer will start playing the new specified sound. It will not stop any sounds that are already playing.
The sound file part of this dialog is the same as in the sound options dialog for objects. See Object sound dialog for details.
