Annoying Victor Sound

[xForceDee]

Sorry if this is in the wrong section but I am using java code and getting a really annoying sound from our victors. We use 2 Victors for our drive train and the rest of our robot using Jaguar (no more victors ). When I use the the joystick the victors make a very high pitched sound. I think it only occurs at really low speeds (just touching the joystick pretty much) however it could just be the motors overpowering it later. Any thoughts on this would be much appreciated.
