Ive always been having a problem with buzzing on my setup, and I decided to finally figure out what was going on. Whenever I connected the cable box to my receiver using the coaxial digital out, I got a major buzz. The kind of buzz that makes it impossible to enjoy what youre watching. And the buzz is the same volume no matter what volume your speakers are set to. And not only that, but it doesnt matter whether youre actually using the digital audio, once the cable touches the socket, it begins to buzz. The cable box doesnt even need to be plugged in! At first I had thought it was the cable box, since using the standard composite cables seemed to have killed the buzz. But then I realized that the buzz was still there, only lower. And the buzz only finally went away when I unplugged the cable wire from the cable box. Once I did that, I could even connect the digital audio just fine...so apparently, all the buzzing is due to the damn cable wire... I did a little research, and it seems as if its a ground loop problem? Im no electrician, and to be honest, I have barely any conception of what that means. All I want to know is what I can do about to stop it. Is it a problem with the cable company's install, or is it bad wiring in my building perhaps? If its the cable company, Ill give them a call in a second, but if its the building, I dont want to bother my landlord about it. In that case, is there anything I can do to alleviate the buzz?
