Double check on layer setup and audio stopping

Hi there,

I have a course up on our LMS that some users have reported similar problems with. They get to the same place and it sounds like the audio is freezing or fading, and the seekbar keeps going with no audio playing and they can't click Next.

I've run this course through SCORM Cloud and it shows as complete.

The slide that's in question has a base layer and several layers. The audio is on the base layer. Three of the layers were set to start by triggers to cue points on the base layer. The 4th one was set to start at a time. I changed the 4th one to start on cue point 4. I don't know what else to consider as I've never used cue points. This was created by someone else.

I did notice that layer 2 had a trigger within it to start the timeline at 0 seconds. If there are triggers on the base layer to start the others, do you need a trigger within each of those layers beyond the base layer to tell it when to start? Might this have been causing problems for some people but not all? Do I need some kind of trigger to keep the base layer audio going? That seems unnecessary because most people show as the course completed.

I'd appreciate any thoughts. Thanks!

(ps: I do not have Pause timeline on base layer or hide objects on base layer checked.)
