I recently bought a Cambridge DTT2500 5.1 Speaker set. When I would play MP3's I would hear slight crackling noises from the rear speakers. I first thought it was the speakers but then when I plugged in headphones into the back of the soundcard I got the same crackling. I just don't know what is causing this noise, its very annoying, but one thing I noticed is that the crackling is persistent when I am doing other things like typing documents while the mp3's are playing. I've tried a Ultra Player and Winamp and the result is the same. Here's my comp's specs:
Pentium III 700 MHz
256 MB RAM
Sound Blaster Live! Value
