I'm getting a high pitched hum from my speakers whenever my stereo is turned on. I have a Sony STRDG720 and a set of Cambridge Soundworks satellite speakers (2.1). I've had the speakers for about 12 years, and the stereo for a little less than a year. I had no problems with this setup from January to May of this year, but when I set it up again after moving to a new place in May, this hum appeared. It isn't so terrible that I can use the system anyway, but it's very noticeable when the other sounds coming through are quiet.

I was wondering if anyone has any recommendations on how best to troubleshoot this problem. I don't currently have another pair of speakers or a receiver to test against. Thanks.

No, it's a house.

Thanks for both those responses, I'll check the frequency of the hum later and report back, though I'm pretty sure it isn't at 60 Hz.

Hi all. Thanks again for the responses. I checked the frequency of the noise and it sits around 1.6 Khz. This is a pretty old house, and most of the outlets are only two-pronged. There are a lot of cables running near the speaker cables, so I suspect it is indeed an interference problem. I'm inclined to just deal with it for now, since I won't live here for too much longer. However, if anyone has any fairly simple ways to reduce/eliminate the problem, I'd be happy to hear them. Thanks.
