ok i figuied it out, anyone who has a sound blaster audigy 4 follow the instrctions given above. However do not use sound blaster 16 when you install. Instead use soundblaster/Compatibles I/o port 220 irq 5 dma 1. This worked for me and i hope it works for you. It got rid of most of the background poping noise. I am using windows xp and i have an sound blaster audigy 4 and i used the instructions given at the beginning of this post.
