White noise on one speaker

One of the rear surround outputs on my receiver causes any speaker that's plugged into it to constantly produce a quiet but noticeable sound of static or white noise. What could be causing this?
I've tried switching the speakers and wiring that are plugged in, but the problem always happens with whatever speaker is plugged in to that output. Adjusting the volume or muting the receiver does not affect the volume of the white noise at all, but plugging headphones into the receiver so it goes on bypass causes it to go away entirely.
The automatic adjustment program on the receiver also thinks that that speaker is further away than it actually is - not sure if that's because the white noise is drowning out the signal or if the signal it's producing is also quieter than it should be.
The receiver's still under warranty, so I could always see about getting a warranty repair. Before I do that, though, is there anything obvious I'm missing to troubleshoot or fix this?
