Background music not working in Articulate Storyline 3 SCORM when uploaded to LMS

Hi everyone.

I am currently working on a project with Articulate Storyline 3 and have administration access to our Moodle Learning Management System environment (LearnBook). 

In my project, I have implemented a soundtrack via including the following code in the story.html file (by opening said file using Notepad). This is the code: 

<audio src="Calm Cinematic Orchestral Underscore 15 min loop.mp3" preload="auto" autoplay loop></audio>

I implement this code near the end of the overall code. I will show you what it looks like,

<script data-main="app/scripts/init.generated" src="html5/lib/scripts/app.min.js"></script>
<audio src="Calm Cinematic Orchestral Underscore 15 min loop.mp3" preload="auto" autoplay loop></audio>
</body>
</html>

When I open my module via the story.html file (default opening into Microsoft Edge), I can hear the background music just fine. The idea is that the same soundtrack is playing throughout the entire presentation, regardless of what slide you're on. I've also edited the soundtrack so it plays for a total time of 15 minutes. It should take a typical user somewhere between 5 - 8 minutes to finish this module. 

However, when I upload the zipped folder into my Moodle LMS environment and then view the resource in Moodle (as if I was a user), I cannot hear the music anymore. If I choose to download my zipped folder from Moodle, the root folder still contains my soundtrack .mp3 file and code in the story.html file. 

Has anyone encountered similar issues? Do you know of any fixes that might be able to help me? The music is quite vital to this module presentation.

Thanks everyone,

-Craig
