Turn up the sound, and a hint, go to full screen. (For those who don't know how, just go to the lower right hand corner of the screen, look for a symbol of four arrows (kinda like + only with arrows on each of the four lines). Click on that and you're in full screen mode. To exit, just push Escape.)
