Speakers intermittently making a buzzing sound

I use Creative GigaWorks T20 speakers.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I've had them for just under a year. They sometimes make a sort of buzzing/warbling noise for a few seconds, then stop. I only notice it when the speakers are not actually playing any audio, because it's quiet and would be drowned out if the speakers were actually in use.

It's not a big problem, just slightly annoying, but I'd like to know if it's indicative of a problem that could get worse, or what's causing it.

They're connected to an Asus Xonar DG sound card, which I've had for about half a year and appears to be working correctly.

I could be wrong, but that sounds like interference, possibly from an outside source such as a very highly overpowered radio transmission (such as a CB Radio with a linear amp.) How often does it happen, or more importantly does it happen at the same time of day every time.

It seems to happen randomly, pretty much whenever they happen to be idle. It probably happens for 4-5 seconds every ~15 minutes.

Is there a major household appliance nearby? Example: a refrigerator on the other side of the wall by the computer.
Still looking for interference; are they plugged into the same circuit as an appliance? (Other then by visual inspection, the only other way I know of to check this is to turn them on and then throw the breaker switch at the breaker/power box and see if they and something major powers down) I was surprised to find my entire home-office shares current with part of my garage and my outside plugs; found out when I tried a window mount air conditioner - using different plugs in different locations.

There's the PC itself about 6 inches away from the speakers. Other than that, everything is at least a full room away. I will test flipping breakers.

If you don't find anything doing the breaker check,then there is a reasonable possibility that the speakers (the small amplifier that they have) are going bad.
Have you Googled your speakers to see if your experience has happened to others?
I have heard nothing bad about the Xonar cards so I would let that be the last of the trouble shooting area, unless some other forum member can input information about this problem.
