Multiple audio players embeded in tooltip

I am trying to embed audio players in a drop-down content tooltip. I will eventually have lots of these on a page.

My problem is this:
When I close the div the sound continues to play.
I can also make them play at the same time.
I would like them to autostart when you open the div, but when I do that they both start at once before you’ve even activated the drop-down content.

I would rather not do the whole site in flash. any help would be appreciated.
