Audio starts playing before timeline starts.

Hello @ all

nearly the whole audio was playing till the timeline starts. Does Anyone has a solution for this?!

I already have posted it as a bug (Case #00415753). The problem is known, but currently no solution is in sight. I don't think that we are the only ones with this problem. So If you have the same thing, in another LMS or in the same, please post it as a bug. Maybe a solution comes up faster.


Problem occurs in HTML5 on iPad only in LMS Context (ILIAS & moodle)

Studio'13: Update 3

Hello Evelyn,

I am actually on then forums right now prepared to post a similar problem.  I am using Presenter 13 Update 5.  I don't know if it's related or not but I get a very wide range of problems with the HTML5 seeker and audio and text syncing in general.   My flash output is great.  My HTML5 output is all over the board as far as the seekbar and text animations displaying in sync with the audio.  I occasionally have a slide where the audio just plays entire before the seekbar starts moving, and then when it does move it is very choppy moving across the screen.  I have other times where it lags behind just slightly, and other times where it starts out in sync but then falls behind.  

Most of these slides do not have graphics or anything, just simply text on a simple powerpoint background with audio added and a basic "fade" animation to sync the text to the audio.   I'm testing with an iPad mini, which does terrible in both safari and chrome, and a Galaxy Note 10 which performs much better than the iPad mini but still lags.   Every great once in a while it will go in sync, but thats literally like 10% of the slides, and there is no consistency in the sense that a slide that perhaps did OK on one attempt, I will try again later and it will do even who knows what.

As a point of reference, I also have mobile Storyline 2 output to compare it with (which I also have well documented quite a few issues with, which I'm hoping many are resolved with the new update) but one thing that I rarely have any issues at all with in my storyline 2 output is the seekbar not keeping up with the audio and the text being terribly out of sync.)

I realize that these are 2 completely different products, but I'm curious if its safe for me to assume that the Storyline2 output is far more efficient than its Presenter counterpart as far as general slide playability is concerned?  I publish using the "standard" settings for each.

Again, I want to re-iterate that Flash has no issues, nor does Storyline 2 even in HTML5 output, for that matter.   My general thought here is that my Galaxy Note 10 has more horsepower than my iPad mini has, and that it takes a very strong device to try to keep that seekbar up with the audio, even though even the Galaxy Note 10 performance I find to be unacceptable as well, just not as bad.

Hi Eric,

I looked further into Evelyns issue, and I see that it was specific to her LMS as well as our team tested in SCORM Cloud, which is an industry standard for testing LMS content and they weren't able to replicate the issue. If you'd like to also share your files with us, we're happy to take a look and you can send them along here.

Hi Ashley, we are upgrading from SCORM 1.2 to TinCan and TinCan is performing much better with Presenter.   I just found it strange that Storyline 2 output had no issues with our Scorm 1.2 implementation but presenter did.  Presenter's playability just seemed more cumbersome.  But I think we have it going well enough with TinCan.

Hi Eric, 

I'm glad to hear you'll be able to utilize TinCan going forward for both - and if you'd like us to take a look at the files we're always happy to. I haven't heard of a difference between how Storyline handles the audio vs. Presenter in the Scorm 1.2 output, but if the issue is consistent and reproducible we'd definitely want to take a look.
