Today we turned on the TV and had great picture - but no sound. Tried mute & unmute, volume +/- , changed channels, etc - nothing worked.
So, I unplugged the Xfinity box, it rebooted and we had sound.
Now, 6 hours later, no sound again and this time reboot did not work.
I will recommend trying this steps first before swapping the box
after trying that steps let us know if you are still having issues
I lost sound on only channel 820, Fox News. Pressing shortcut key D on my XR2 remote control restored the sound. No matter what channel I am tuned to, pressing key D mutes channel 820. So, if I accidentally bump key D, I may not immediatelly realize that channel 820 has been muted.
I cannot get sound on WCYB during any local broadcasts of news (during The Today Show there is sound) and afternoon syndicated shows. I have a new Samsung TV and a new cable/Dvr box. The channel has sound on the tv downstairs. I have looked at Languages and I am set on English. All other channels are fine. DVR failed to record Bill Board Music Awards on that network last night. I have successfully recorded on the DVR all other times. Any advice would be appreciated.
I fixed it by googling and reading this forum. I knew that it was a language issue but just couldn’t figure out how to access that with the new remote. So I am writing to thank myself for a job 👍 well done through perseverance. I just knew it wasn’t Comcast or the tv network. It was all in the default audio setting. Happy.
No sound AGAIN, have checked cables , and all plugs. "refreshed' for weeks Perfect Picture again but no sound. This audio problem seems to be happening to alot of customers of comcast. Expensive service to not be working. (No customer service email correspondance only chat or phone delays ... want what I am paying for to service me.)
