I just recently purchased a new tv and hooked it up to my joey and when i change the channel there is a loud high pitched beeping sound. It was hooked up with rca cable to my old tv and no weird sound. Its now hooked up with hdmi cable and right before the picture returns after changing channel it makes this loud beeping noise. I switched hdmi cables and reset the joey. Noise still occurs. wondering if there is some setting that is causing this?
