Flash和SWFObject2在后台选项卡中停止Flash音频

I use SWFObject 2.2 to play sounds for an AJAX based game I have made. I used to use SWFObject 1, and everything worked fine, but when I updated my game, I updated to 2.2. Now, when users try to listen to music on Youtube or Pandora in another tab on Firefox while playing the game, they can't unless they have that tab selected.I use SWFObject 2.2 to play sounds for an AJAX
