MP3 sound file doesn't play in HTML5

Sep 10, 2018

I have a story file that contains a couple of MP3 sound file.  The sound plays in preview mode, and will play if I save as CD, but it doesn't play in HTML5.  Can anyone help with this?

When I publish to CD, the sound does work, but I need to publish to LMS.  The full story has narration that was recorded in Storyline and the narration plays, its just these MP3 files that don't play.  I even tried recording the MP3 sounds with a mic into Storyline and they still don't play.  My browser choices are Chrome and IE.

On an unrelated note, where do you find the link to upload to review?

Thanks for you help.

Hi Dan,

Testing content locally that has been published for Web or LMS, may cause you to encounter security or other browser restrictions and content won't play back as you'd expect. I'd recommend uploading to your LMS (or use a site like SCORM Cloud for free, easy testing) to confirm that everything is working as you'd expect!

Thanks Dan.

I'd upload the zipped published output to your LMS and take a look there to see how the audio is working. You could use SCORM Cloud if needed for testing if the file is under 100mb.

When you view a Storyline 360 course on your local hard drive, you'll encounter security restrictions from the computer, web browser, Flash Player, and network that can cause various features of the course to fail.

Thank you to everyone who responded to my post. I found that by inserting a slide, ahead of the original slide, that you have to click NEXT on, then the rest of the project plays correctly.  But if the first slide has a trigger to automatically advance to the next slide, the project doesn't play correctly.  Since Phil was able to play it without any issue, I sent it to a coworker who also reported that it played correctly for them.  This makes me think there must be some issue with my local computer. 

Again, thanks for everyone's time and advice.
