Audio stops playing on slides after added to LMS

Sorry to bring this back up....
I have a project where the title slide audio keeps cutting off 1-2 seconds into the project launching - after publishing to our LMS (scorm 1.2, html5 with flash backup) or when reviewing in scorm cloud or in Articulate Review - ONLY in CHROME. It always works fine in preview mode and in other browsers on PC and mobile devices - it appears to be just chrome. 

The audio will play on the Title slide when I replay it.  It is thankfully just music on our title slide, but it is not a good first impression for someone taking the course - it is definitely noticeable that it cuts off and the slide graphics still move along as normal.  Plus on the title slide we don't have a player showing, so they can't replay it unless they know to go to the menu, and why would they replay it anyway.  Regardless, ALL the other audio files play fine.  

THE ONLY difference I just realized is the first slide is an mp3, the rest are .wav files.
What could be happening? Is this a known issue with Chrome that the mp3 files are 'glitchy'?

Here are my versions:
Chrome: Version 64.0.3282.119 (Official Build) (64-bit)
Storyline 360: 3.12.14533.0

Thanks for the help!
