Background: My brother and I use a program called Picophone as a telephone while he is going to school in alaska. His microphone makes a constant buzzing, staticky noise, which is rather annoying -- I keep telling him to get a new one --lol. Whenever he plays counter-strike MY sound quality suddenly gets horrible. When he starts a program that loads his cpu heavily the strange noise gets quieter. When he starts a program that uses the ehternet card (specifically HLSW, a utility to keep tabs on CS servers (like gamespy)) the noise gets louder. If he plays UT2003, however, the "symptoms" are not repeated. My question is: WHAT could be causing this problem and is it fixable? I thought at first that it was his microphone causing it, but now I believe it's something else. Feel free to ask questions, as I do have more to tell if it's needed.
