No sound for all channels
Not getting sound from any channels. I've done the system refresh, cable box reboot. Checked input, etc. Occasionally, like once every 20 mins or so, I would get a 1 sec of sound and then silence again. I'm guessing the cable box needs replacing?

is the set top box connected to the TV or to a sound bar/receiver? do you use a sound bar or receiver? if the set top box is connected to HDMI1 (one) or HDMI2 (two) on your TV, do your TV speakers have sound?

It was connected to a soundbar, but then I disconnected the soundbar. Same result, no sound. About an hour later the sound came back on, so I assumed that the problem was on Comcasts end.

Did you connect the HDMI cable to the proper port on the television?
Many tv's have one HDMI to DVI port. That port passes a HD signal but NO AUDIO. You can use it if you connect a additional DIGITAL cable (or Optical cable) to get stereo or 5.1 surround sound.
Otherwise connect to a true HDMI port.

How many people have a fully connected, fully functional TV with sound walk out of the room to come back and have to reconnect cables? I mean seriously this is horrific advice!
did not help me at all! 😡
