Sorry, had a closer look at your timeline screenshot. You really need to read my blogs about Pausing the Timeline. You have an interactive object (green timeline) which is pausing the slide at 1,5secs. It is possible to pause the slide audio at that moment, but I suspect you didn’t do it in the Properties panel, so audio will continue but the rest of the objects is pausing. What is the purpose of that button, please?

only to enter as the line is read nothing important just jazzing up the page since the rest of the file is not interactive

Extend its timeline (button) till the end of the slide, which can be done after selecting the timeline with CTRL-E.

Then grab the pausing point (vertical line to the right of the pause symbol) and drag it toward the right, until you are after the last object has entered. Somehing like 11,5secs (you can also do that in the Timing panel).

BTW I see more incongruencies in that timeline: the Effects are longer than the presence of the object, which means that the effect never will be totally done.

Really need some training about the Timeline, here are some links:

Or watch this movie:

I posted an answer, but since it has hyperlinks, you’ll have to be patient, has to be approved 

Will repeat partially without links:

Select that green timeline, and extend it till the end of the slide with CTRL-E.

Look for the pausing point: thin vertical line to the right of the pausing symbol. Drag it with the mouse till it is after the last object timeline (11,5sec?). You can do the same in the Timing panel, up to you.

Warning: your effects take longer than the objects, which means they will only partially been done. You don’t want the effect timeline to be longer than the object timeline.

I though Storyline had a timeline as well, but probably not as multi-featured as Captivate’s.

Ok. Let me give it a try. thanks .  I’ll look for the links too.

Answer with links still not approved. You can search for Timeline on this portal, most of my blogs will show up. Have interactive movies as well.

You are awesome Lieve!! It worked!!

Thank you.

Timeline is one of my favourite topics, you really have to learn about it. It IS the real core of Captivate, all my basic trainings start with real focus on understanding that panel.Since my answer from yesterday is still not approved, trying again to post some links:Captivate’s Timeline   interactive movie https://elearning.adobe.com/2017/01/all-you-have-to-know-about-captivate-timelines-in-a-cptx-project/https://elearning.adobe.com/2017/02/pause-captivates-timeline/https://elearning.adobe.com/2018/04/tweak-timeline-4-easy-workflows/https://elearning.adobe.com/2018/06/pausing-timeline-audio-clips/ 

LMS is playing in a web browser, so the problem will be the same after disappearance of the Flash Player, unless you can force your learners never to use a recent web browser.

Terminology problem: you do not use an animation, but an effect on an arrow, which is not using the Flash player. That is OK.

Audio has to be loaded On Enter of the slide, and depending on its size that can take a little while which can cause unsynchronizing with the objects on the slide. To avoid that move the audio timeline a little bit to the right (0,3secs) and synchronize in that position.
