Audio controls/voice over narration
Are there audio controls that we can add to a page. We have voice over narration that we want the user to be able to turn on and off. At present we have created two buttons - on and off button for each function - creating a media button on clicking on the "on" graphic starts the media and click on "off" stops the media (audio). is this the best way to do this - ideally we would like one button that you can click on once to turn on and then again to turn off.
We would also like to be able to turn the voice over "on" on one page and then for it to continue being on for all following screens until the user clicks on the "off" button and vis versa. Is that possible to do this or any similar functionality that we can do to achieve that?
Any help much appreciated.
