Well this problem is so random.
I've searched all over the web for specific but apparently the problem is about as rare as a finding a [content removed by moderator]
On my manager's desk are a pare of basic every day speakers, two of them, left and right. It has a power cord and an audio cord to the computer. Well randomly about two weeks ago at various times of the day (but seems to be increasing in frequency) the speakers suddenly output some radio signal! It actually comes in fairly clear, usually a talk show or a commercial or even music is heard. It only lasts a numbers of seconds and then goes away.
Thinking this was faulty power cord or wiring in the speakers, I just bought a really nice two-speaker set from Creative and hooked that up. And the radio signal continues!
My suspicion at this point is that the rouge signal is coming from the the APC UPS that the speakers are plugged in to. I haven't switched it yet but this has got to be one of the weirder things I've seen, because everybody else has speakers too, and the same battery backups, and only his speakers get the signal.
