Switch back to comcast from att 3 weeks ago.
Everything worked fine with att.
Now on comcast there is choppy audio output from both the digital optical and coax output to my receiver.
I moved to the cable output to the DVD digital input on the receiver and same thing. Tested my DVD and it works fine. ( DVD is using optical out)
Comcast tech came out and replaced box, put an amplifier on the line. Said the signal was good.
When he hooked it up HDMI to tv it worked fine.
Panasonic Th42PX600U plasma.

RNG??? cable box.

Thanks in advance.
