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?
All of our 5 TV's have a muffled, over amplified, sound to them. All are connected differently such as with a DVR, or, Sound system, or, just to Comcast cable. It makes it hard to hear words and is worse on some Channels than others, but, all Channels are affected.
The problem started 3 years ago about the time the Digital change over occurred. Also, at that time a Comcast repairman had to go into a junction box near us and found a problem and replaced a Part, plus found water in the box, which had been causing extreme pixels on all our 5 TV's. The pixlel problem disappeared and after 8 days of no TV at all, we again could watch our TV's.
Coincidence?
Comcast has finally sent a company repairman a few days ago who spent 2 hours at our house and checked out the Telephone pole cable finding two repairs to be done, then lowered a booster Amplifier on the house, checked under the house, and listened to the sound on all 5 TV's. Still the muffled effect.
I asked fora check on the Junction box, but, have heard nothing more. I left a phone message for this Repairman, but, no answer back.
