Hi Raleigh!

I do not have the time to explore your uploaded Hype project in depth but I noticed You are using “.mp3” files… according to this post by @Daniel iBooks requires “.m4a” (ACC) files:

Adding Audio and Video to your iBooks Widget

Also iOS does not allow volume to be set by JavaScript - that includes muting. Just below is the link to the “iOS-Specific Considerations” page of the Apple Developer site re: Audio & Video.

Also - as You probably know - your “control” buttons at the bottom of the page overlap and cover each other when the page is narrowed.
