Articulate Storyline 360- Music across specific slides - how to stop it?

OK - UPDATE for anyone following this thread.

I have the music working exactly as I'd hoped, across slides and stopping when it's supposed to. Working perfectly. Woo hoo!

Export it from Storyline via "web"-- then I copy/paste the background music file to the exported Story Content folder. When I launch the story file-- again, it works perfectly.

HOWEVER... I have tried numerous times to export this to TALENT LMS - where the full course (of which this is one module) lives.  But on TalentLMS, the MUSIC doesn't play, ever.

Before zipping the file, I copy/paste the background music file into the storyline output folder. I've tried to additionally paste it to the story_content folder and also the LMS folder.

Nothing works. When I launch the game on Talent LMS, all my other audio sfx sounds work EXCEPT the background music audio.

Anybody know TalentLMS and what I am missing?
