Coding for multiple bespoke audio players on one page.

I have 12 audio players in an iframe. When a player is clicked it must do the following: play the audio stop any other audio send a variable to another iframe. If the player is clicked a second time it must stop the audio (not pause) I currently have this working on an ipad 1 but on ipad 2 and 3 mutiple players play simultaneously. I have included the current coding. I am currently using javascript but you can use jquery or what ever needs to be used to get the job done.
