You may need an RF filter between your AC outlet and your PC's power cord to eliminate it.

Answer 2

Answer 3

ive seen were a cheap set of speakers can actually pickup singles from local radio stations, IT,s harmless to your computer, and is caused by bad shielding in the speakers!  

Answer 4

Max ... I am having the same problem.  It started ~1 or 2 weeks ago.  Can't identify the source.

I will continue to investigate and share with you if I find an answer.

Update: My problem seems to have been caused by a "freeware" utility that I installed a couple of weeks ago.  It was packaged as "audio-mid-recorder.exe" and it rips the audio track from AVI files to MP3.  I assume the software was somehow interacting with my system's audio drivers.  I removed it yesterday and I haven't heard the unknown audio since.  Perhaps this will give you a clue as to what is going on in your system.  Good luck.
