title: HTML5/JQueryMobile: Audio still playing if i click back button
body: <p>i wrote a simple gallery which plays an audio file if available.
  By clicking on the current pic it will simply jump back to index and stop playing the audio.
  But if i click the back button on the browser the audio is still playing, even if i jump to another page with a simple  tag pointing to another page.</p>
  
  <p>I think the problem is that jquery mobile is preloading pages and then showing it up at once after loading. I like the way jquery mobuile is preloading pages, but i would like to stop the audio if i click on the browsers back button.</p>
  
  <p>I tried catching the back button with the $(window).unload() event, but it doesnt work. How can i totally unload the page (incl. audio) i want to leave?</p>
