A developer has created a Flash presentation for us using Macromedia Flash MX. It is about 3 minutes long and consists of numerous scenes, each of which has its own separate narration file. The project is done except for one unresolved issue.
We requested that a sound on/off button be added to the presentation so users could turn the narration off at any time. The developer responded by saying, "If we do that each audio file would have to be programmed separately, and we still would not be able to guarantee that it would work correctly. This is a problem with the software that we have created the presentation in." My suspicion is that the developer doesn't know everything there is to know about Macromedia Flash MX, but I am not a Flash expert so I don't really know.
I have two questions: (1) Is it possible to add a global sound toggle-switch to the presentation, even though as I understand it the narration consists of a series of event sounds? (2) If so, what instructions can I give the developer? (The URL of a page in an online reference guide? Actual code and programming guidelines?)
