I know this isn't a computer question, but figured there might be some on the list who have some expertise that can help me figure out this pesky question.
Two years ago we remodeled our basement, and I ran speaker cables for a 7.1 setup. I used good quality 14AWG CL2 cable, and HDMI for the video. Everything goes back to a Yamaha A/V receiver. Almost immediately I noticed that there was faint sounds coming from the speakers unrelated to what was playing. It's gotten worse over time, to the point where now it is clearly identifiable as WFED AM 1500 radio station, about 10 miles away. It's loud and clear to the point where the radio is just as loud as the source audio with volume set to -40 dB, and if the volume is set lower than that the radio is louder. The radio comes through no matter what I seem to do. Muting the A/V receiver, switching inputs, it's still there. Clearly there's some sort of interference going on, but I can't seem to identify the source. It comes through all the speakers at about equal level, suggesting it's being broadcast and amplified from the receiver and not just randomly being picked up by the wires. The wires are not extraordinarily long - about 20 ft for the rear surrounds. I actually had the same receiver in a previous house that was much closer to the radio station, but didn't have any problems. All the inputs to the receiver are HDMI (Fios TV box, HTPC, WiiU), so it's hard to see how they could be picking up interference. Thoughts? Suggestions? --------- Brian
