I just discovered this thread and am "intuiting" what the content of the prior messages in this thread were about but here's my two cents anyway. The other responses, appended below, also offer advice you should heed.
Try shielded cable or, if you are using shielded cable, try unshielded cable. Also, starting with the wall outlet, test for proper grounding of the wall outlet and every component connected to the wall outlet. Try moving the PC to another outlet on another circuit in as distant a location on the premises as possible. If all fails, consider purchasing a high quality filter that either reduces and/or eliminates RF and/or EMI on the power line. I would avoid the Shack and instead search for high quality filters from a company such as Black Box, located somewhere in Pennsylvania. The filter will set you back around twenty bucks--certainly no more than thirty bucks, including shipping. Oh yeah: check for the possibility that your speaker wires and/or microphone wire and/or any other wires connected to your PC are not acting as an antenna, thereby contributing to the shmutz; you might find it necessary, for example, to put a filter on each spealker wire nearest the point where they begin--furthest from the speakers. Disconnect your speakers and test using headphones. Is your case shell constructed of metal, rated to block RF and does your case have a window or other open aperture that leaks RF that can be prevented with a piece of metal or by reorienting the case? Most of this troubleshooting requires either detaching one or more connections at a time or, better yet, detach every cable you can and then start attaching the cables one at a time until you either identify a culprit or eliminate cables as a source of schmutz. And be certain that every connector is clean and securely attached before beginning the hunt. I had a similar problem a couple of years ago, it drove me nuts, took a couple of hours each day over several days to diagnose and correct; it wasn't a fun time but I had to correct it because the schmutz was fatiguing. Good luck! cfv ----- Original Message ----- From: "Geoff Eden" <[EMAIL PROTECTED]> To: "PC audio discussion list.
