To my knowledge there are no direct controls for audio. There are however controls available for video. So, if you convert your audio into an audio only video, then you will have the ability to pause and stop the audio playback.
And, if you want it to play continuously throughout each page, it has to be turned on in the Layers Pallete on those pages. It doesnt have to be visible in the artboard, unless you want to be able to pause/play it.
