More information. A Neighbor stated she does not have any problems with her TV audio and was surprised at the bad audio we had as she stood and listened to our TV's. I tried some experiments. I have 200 music files downloaded from the Internet before Comcast took over. This music is now on a SanDisk Player and I listen while doing my 5 mile early morning Run. The music is perfectly clear, not bass distorted as we hear on our Cable. It is the sound just like we were hearing before the Digital conversion and the repair work of a Comcast employee.

I then played some vinyl LP's on a phonograph that is not in any way hooked to a Comcast cable and the sound also was perfect, no adulteration as we hear from our TV's.

Is there such a thing as an electrical problem? Something plugged into a line that affects Audio through the house?

Who could we call to make a visit here that knows more than Comcast?
