Audio in EPUB

Here's the situation. I have a nice, fixed-layout EPUB. Art and text display perfectly. Audio is beautiful. Standard slider control at the bottom left of the landscape pages, with opacity lowered a little so they won't be too obtrusive.

The author has seen the book as a PDF and as an EPUB. In the PDF, which was laid out in InDesign in standard book pages, and exported as spreads, the audio is set to autoplay and will turn off when a page is turned. Technically, it's the spread that is turned, but Acrobat sees it as a single page. Perfect. Would rather not do autoplay, but that's not my call.

In the EPUB, though, the individual pages, which are individual HTML files that contain the backgrounds of each spread (see the lynda.com Fixed Layout EPUB course) with all elements positioned absolutely by CSS, there does not seem to be a way to get reader software (tried iBooks and Readium) to see these as anything other than pages of a spread. I have the orientation-lock set to landscape and open-to-spread set to false. Doesn't make any difference. What I get are landscape pages that display properly but BEHAVE as if they are one-half of a spread. Consequently, the audio for BOTH pages will autoplay if I leave that setting on. With manual controls, the sound will play on the verso when turned on, but continues playing when I "turn" to the recto, which of course is the other side of the spread I didn't want. When I turn the recto, both sounds turn off.

You can see both of these files here:

I hope someone can tell me how to deliver up individual sheet EPUBs. I know a page implies a front and a back, but if HTML pages don't behave this way, I'm guessing it has to do with the reader software.
