Sound performance issues

Hi all,

I’m developing this game: http://www.gamestunt.com/CSG/
There’s a bit of a problem with the present bounce sound - if you play the game, you’ll notice a tiny pause when the present bounces off the plane which is introduced by me playing the sound:

boing.play (0 , 0);

Is there anything I can do about this?

Any help appreciated
