Intro to Games Development

Hi,

I've been messing around with some simple code as a practice model for our game Panzer Blitz. This practice was set up with an orb object bouncing around the screen making a sound when it reaches/"hits" the edges of the screen. However once it was run there is a very big problem. There is about a half second delay on the bounce and the sound being played :(. I've looked at setting up the mixer using pre_init, setting parameters like the freq, channels etc. and everything pretty much on the pygame page @ http://www.pygame.org/docs/ref/mixer.html

I've attached a zip file with all the stuff you need please any help with sorting out this lag would be greatly appreciated :D
