Storyline 360 courses - audio not playing or very delayed in published output

Hi, I already submitted a case for this and support and although they have been able to duplicate the issue, they haven't been able to track down a solution yet so I'm hoping someone else is having this problem too:

On random slides the audio is either delayed or not playing at all after published and uploaded to LMS. It works perfectly fine in preview or if I view the published output locally. It just doesn't work when I test in my LMS (Saba). I've also tested in SCORM Cloud and it doesn't work there either.

I've tried everything from uninstalling SL360 and reinstalling, starting a new project and importing the old, re-coverting from Storyline 2 to 360. I even tried recreating the affected slides from scratch but the audio is still messed up on those certain slides. It only happens with SL360. If I keep the project in SL2 and republish it, it works fine.

I am a Mac user and operate SL using Parallels and Windows 7. I have my shared profile disabled, I operate locally on the windows side and followed all the suggested instructions when using SL with a Mac. 

So basically, I'm stumped. Anyone out there experiencing anything similar? This issue has affected 2 separate courses that need to be updated asap so I'm sort of desperate here.

Oh, one more thing. If I add a seekbar to that slide and scrub either back or forth, it starts working immediately. And yes, I even tried adding a trigger to those slides to play audio when timeline starts. I also added the audio to a layer and triggered to play that layer when timeline starts and that doesn't work either. As you can see, I've been spending hours on this annoying issue.
