Embed audio file into slider, not individual slides

Hi. If you go to the page show, you will see an auto-play audio track embedded at the top of the page text. I want to move that to just below the entire slider frame I put at the top, but all I can seem to do is put it as captions on each slide. The problem with that is that the autoplay reloads with each individual slide. Any way of doing this?
