Problem with HTML 5 Output

Hey Guys

I have recently been working on a system that requires use to use the HTML5 output files of our courses (as the flash output does not link to the local files correctly for what we need to do, but that's another story). In the module we are working one at the moment, Some of the audio plays on slides that its has not been assigned too.

For Instance, I have embedded I piece of audio  into side 7 and one into slide 8.

in the flash output: audio playing in there consecutive slides

in HTML output: audio plays in slide7 and then repeats halfway through slide 8, while the slide 8 audio is playing.

Has anyone come across this before?
