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?

Re: No sound for all channels

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.

Re: No sound for all channels

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.
