I've got a course in which all of the slides have a narration for the text, and some slides that have videos with a soundtrack (narrated). Obviously, the sound for each slide can be turned on or off by the learner, as can the sound for each video.
Is there a way to allow the learner to opt out of narration for all of the course, while still having the video soundtracks play?
I'd like the soundtrack to be mandatory listening, but the narration optional.
Perhaps too much to ask, but I thought I'd put it out there. Any ideas?
