    Subwoofer noise interference
    Can anyone help identify the problem I am having? There is a very loud "thumping"
    sound I experience whenever I change the function knob i.e.. from DVD to CD or whatever, and when the receiver switches from different surround channels i.e...pro logic to dolby digital. I have a Yamaha RX-640 receiver and a Klipsch RW-8 Sub. Any help that I can
    get would be appreciated.
