Audio Delay When Published But Not When Previewed
I have a slide with audio that should begin playing when the timeline on the slide begins. When I preview the slide, it works as it should. When I publish the course, the audio is delayed by 10-15 s...
I have the same problem. The audio on the first slide is delayed, throwing off my synchronized bullet points. When I preview the slide, it works as it should. When I publish the course, the audio is delayed by 10-15 seconds. It is also happening on other slides. I have these slides auto-advancing and sometimes the slide advances before the audio finishes. I know if I change the slides to manually advancing, the issue is not noticeable, but my customer does want that. I searched through the forum and found many discussions (on this topic) that are very old. This was the most recent one I could find. I did not see a comment where Articulate acknowledged the issue and stated a plan to fix not did I see a suitable fix for it. BTW, I have the newest version of Storyline 360.
Hi Brandan,
Thanks so much for reaching out about this and providing such detail!
- Are you working on your local hard drive?
- Are you publishing your course for LMS viewing?
It will be helpful for us to do some further testing if you're comfortable sharing your file. You can upload it here or privately in a support case, and we'll delete it from our systems as soon as we're done troubleshooting.
I've experienced this issue just as Brandan describes it, using up to date SL360 in more than one course. This happens to courses published in Review and also to our LMS. It happens in Chrome and in Edge. It is inconsistent for me and for other users - sometimes a slide is delayed, and sometimes that same slide is not. Some delayed audio starts without a trigger, some delayed audio starts with a trigger. Some slides auto-advance and others do not. We've experienced the issue with imported audio, audio recorded within SL360, audio generated within SL360 using text-to-speech.
The best way to describe it is similar to the buffering you might experience in a video, except that the only delay is the audio. The visual (animation, screen recording, etc.) moves on the timeline as expected.
Hi DebbieSiguaw!
Sorry to hear you're also experiencing delayed audio from your Storyline courses!
Since the behavior is widespread, it could possibly be related to internet connectivity speeds. Slower networks can have an effect on loading times, for audio elements within a course. Are you able to test the issue across different networks? Also, does clearing the browser's cache make any improvement? It should help the browser purge cached files, to load audio and video more quickly.
If you're comfortable sharing one of the affected .story files, we'd be happy to take a closer look and test it on our end. Feel free to upload a copy here in the discussion or privately through a support case.
