No sound in FF & no show in Apple Stuff?

Can you tell me why the [COLOR=Red]sound[/COLOR] [COLOR=Red]does not play[/COLOR] in FireFox but does in Chrome & Safari?
The sound is not embeded in DW but is in the Flash. Also I want to know what is wrong with my DW script that it will not play on Apple Ipads & Iphone?
