JQery /HTML5 Audio file Fade

JQery /HTML5 Audio file Fade

hi
About a year ago I was involved with Jakecigar's great scrollsound control code found on the post  'Audio fading in and out scroll position' and 'Jquery/HTML5 Audio file Fade 2'


I cannot figure out how to implement the pause/play functionality. I would like to pause and then play ALL of the 'soundTour' music files ( regardless of where the user is scrolled to on the browser page. In other words, pause  all sounds. I've managed to stop the sound with

  $('#soundTour3,#soundTour2,#soundTour1').scrollPlay({
play:false
});
});  

But to reactivate the sound I'm at a loss. I've tried :

$('#soundTour3,#soundTour2,#soundTour1').scrollPlay({
play:true
});
 });  

But that doesn't work. Any suggestions? Also to further complicate things. The user may or may not click on an entirely different set of sound files available on the site ( independant to the soundscroll music ). I don't want to interfere with these sounds. As well, if the user clicks one of the independant sounds it must pause (interrupt) the sound scroll sound. Don't want 2 songs playing at the same time. 

Any help would be appreciated,
Jaimmy
