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'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.
