Separate Video and Audio file don't sync after publishing


I'm using Storyline 2 and in one of my course, I used separate video (mp4) files and added later as mp3. In the timeline, my mp4 and mp3 files are separate. 

While in preview the slides work fine, after publishing the same slides with separate video & audio, don't play as expected. In fact, the video plays while the audio doesn't. If I move the seekbar back and forth, the slides work fine.

Any idea why this happens, and how can I make sure that my learners don't face the same issue.

Hey Deepak!

Thanks for the update here, I'm glad it's working for you in your LMS.

If you were viewing the published course on your local computer, that could be why you ran into erratic behavior. When viewing locally, you'll encounter security restrictions from the computer, web browser, Flash Player, and network that'll cause various features of your content to fail. 

The best way to avoid this is always testing in the environment the course is published for- so in this case uploading to your LMS was the perfect move. ☺️

Good luck with the rest of your project, and don't hesitate to reach out here if you run into any other hiccups!
