![]() When I disconnect the satelite cable, the hum goes away. I'm experiencing a humming problem when I integrate my direct tv into my audio system. I had the same problem with a Mitsubishi Television and never could eliminate it. So, my first thought it to give DirecTV a call and see if they'll send me a new receiver. Polarity is good and I don't get any hum when the DVR HDMI is removed. I havent tried it, but I'm pretty sure I can eliminate it by using a fiber or coax connection for audio to the pre/pro and running the HDMI for video directly to the TV, but I'd lose a lot of convenience as regards HDMI switching. Though I may be wrong as it's about a 60Hz hum. I'm not sure it's a ground loop, but rather, I'm guessing it's noise on the ground induced by the hard drive. As soon as I do, I pick up a fairly loud hum. Now, the not so good news and something I could use some help with.Īll is good until I plug the HDMI cable from my DirecTV DVR to the pre/pro.
