This is a little off-topic, but I hope you don't mind. I get quite a lot of noise from my soundcard. There is a pulsing that sounds something like a very fast morse code at a consistent pitch, and it's unacceptably loud. I notice variations in this noise based on how I move my mouse. At first I thought this was just because of my shoddy 5-year-old Soundblaster Live, but I have a new Audiophile 2496 and it does the same thing. Today I tried removing the stereo mini plug from my soundcard and touching it to the metal on my case. The sound was nearly identical. >From the little that I know about electronics, I conclude that the problem is voltage fluctuations in the metal of the case. Does this mean my case needs to be grounded somehow? What can I do to fix this problem? Josh
