Is there any way to fast forward sound in a SCORM?

Why would you want that? You create narration but learners don't need to listen? Sorry, I don't want to blame anyone but it makes me just curious because I suspect there is something else that you want to achieve. I may be wrong of course. Let me explain: you may allow the learner to come back to a slide which has already been viewed and listened to completely, but you want to avoid that they need to listen again to the full narration? Is that the case? If  yes, you need a way for a different behavior between the first visit to the slide and later visits. There are several ways to achieve this, but here is a possibility described especially for Audio:

In a later post I explain how to use a shared action to make it easier to apply this workflow to multiple slides (projects):
