How can I Toggle Sound On/Off

Hi Heroes,

Please excuse my bad memory and even worse search acumen. I believe there is a thread or tutorial about what I need, but I can't find it.

I'm developing a course and I want to allow the learner to set their own preferences for listening to narration or turning it off and reading the screen text. I hate listing to what I'm reading and it just produces incongruous cognitive overload!

Here's what I want to do: I want a page that asks the learner to click on one of two buttons (course with narration + course without narration). If the learner clicks without narration, they will not hear the narration. Clicking with narration, they will hear the narration.

ALSO...I want the learner to be able to toggle back and forth between sound/no sound settings on any page.

Variable, yes. Logic and what to put on what page/master I'm not so good at.

Thoughts?

Thanks,

Rick

Hi Rick:

Create a Global True / False Variable named narration.

Set the variable to False as its initial value.

Create your initial page with the 2 buttons you want.

The "yes, play audio button" will have a trigger to set the variable to true.

The "no, do not play audio button" will have a trigger to set the variable to false.

NOTE: These 2 buttons will be used in all other slides as well (maybe you want to copy them to a master slide).

On every slide that contains narration...

Create a slide trigger to stop (or pause) media with the condition IF variable narration has a value of no.

Hope this gets you on the right track.

Best Regards,

Dennis Hall
