Audio Problems When Playing Back on iPad (HTML5)

I have a module published for HTML5 output on mobile devices (specifically iPads) but the audio  has serious playback issues.  When you navigate to a slide containing an MP4 movie w/audio, and then navigate away to another slide that contains a WAV audio file, the audio plays garbled, robotic, and very slowly until it cuts out completely.  If you then navigate to any other slide with an audio track, the audio no longer plays at all on any slide with audio.  I have unsuccessfully tried several solutions: Specifically, making sure that my audio is WAV at 16-bit, 44 kHz, PCM-encoded.  My client requires that HTML5 and NOT the Articulate Mobile Player be used by their customers.  I would very much appreciate if anyone could offer some advice on how to fix this problem.

Hi Curt!

You may find that audio in your Articulate Storyline 2 courses doesn't always play as expected in HTML5 output when viewed on Apple iOS 9 iPads and iPhones. We added support for iOS 9 in Update 7 for Storyline 2. See this article for details on how to update your Storyline software and your published courses.
