Audio and animation synch issues on Mobile devices (HTML5)
Oct 21, 2014
We are experiencing audio synchronization issues when publishing to HTML5 and viewing our content over tablets (we tested with iPad and Samsung Galaxy). We are NOT able to view the content in the Articulate Player app, because our LMS does NOT support Tin Can (we have to stick to SCORM).
What happens is that the audio and screen animation will play OK and keep in synch some of the time, then on other screens the audio will "disappear" and the text bullets will continue to build, and then on other screens the audio will start, stop, restart and the on-screen animations (such as bullet builds) will then be out of synch. None of this behavior occurs on a PC or MAC (just mobile devices).
Does anyone have some best practices out there for preventing this? For example, should we NOT use auto- advance? Any other "tricks?"

Hi Mark!
For starters, can you verify that you are utilizing the latest update to Presenter '13, which is now Update 4?
We have had many improvements to both animations and HTML5 in the last two updates.
Yep, we are using Update 4 (1409.422).
Would you be able to share your Articulate Package so that we can have a look. If you can't share it in the forums, please share it here.
Thanks Leslie--I have uploaded the package to Articulate Support (your second link).
Thanks for sharing that information Mark, I see your case (00430700) and you should be hearing from someone soon.
Leslie, I would love to talk to someone as well. I'm having the same issue. However, when I looked at the compatibility matrix, it shows that audio and animation together in a slide and published to HTML5 are not compatible with Safari. I have disabled auto-advance and that helped the issue I had earlier where iPads would play no audio at all. Now, the issue is that the audio starts before the animation on every single slide created in Articulate (minus the videos I have inserted into slides via articulate - those work fine. And after the audio is finished for that slide, the animation keeps running until it's finished so there's a major synchronization issue. I have been desperately trying to find a solution for this as we have sold about 50 seats to a customer who is planning to have everyone take the course on company issued iPads.
Thank you!
Hi Julia,
It looks like I may also have responded to you in a few other threads and shared directions on how to provide your Presenter package here.
Hi Ashley,
I couldn't attach a file to the page. Whenever I tried and pressed reply, I was sent to a blank page that said the page was unable to load. Is there another way I can send this file?
Thank you,
