Invite a Comcast Tech? Pay $ 70 or $150 for sometimes a not-so well informed person to tell you that:
Signal is weak (why don't I have pxelation?)
It will improve in a couple of days
It is a problem of your equipment. All I am responsible for is to make your TV work
... and please watch you bill for the charge

I suspect X1 boxes need an software update. I had a DTA connected to thid old Sharp TV. My wife has some earring issues so I installed an old Vizio 5.1 sound bar. No problems for more than one year. Last month I had an upgrade from Comcast. I got a ste-top box that can communicate with the DVR.
No problems with the image or with the communications with the DVR. How about sound? No sound whatsoever from the Vizio Sound Bar. When the Tech installed it he told me that in a couple of days the problem would go away. It did not.
Why I accuse X1? Well before with the scalled dowt small DTA I had no problems with sound comming from the Vizio Sound Bar. Now nothing. But how I am sure it is the X1 set-top box? Well I have 3 other devices generating image and sound to this system:
1. Internal off the air broadcast: I can have about 40 local channels. Digital image: pristine, sound from the Vizio belissimo 1.
2. Google Chromescast dongle: No problem whatsoever.
3. Ancient Pilllips DVR player (not even BlueRay); Plays DVD with nice image and wonderful sound.
4. Comcast Infinity X1 set-to-box: Image OK. Sound? only from the louzy speakers of the Sharp TV.
Please, please, please: do not tell me to reprogram, reset, rebot the REMOTE CONTROL. The X1 remote is fine. It controls the TV (on an off) and the Vizio Sound bar 5.1 (on and off and volume) so there is not issue with the remote control.
By the way I have read that X1 has issues with Samsoung, Sony and Yahamaha sound bar also.
