At work so not in front of it right now unfortunately so I'll have to try those steps when I get home.
-I did confirm it happens on all channels as that was something i checked to make sure it just wasn't some random station. No volume to any station.
- I did note that when i unhooked the audio cables and placed them back in, if I got a loud humming noise from the TV, that's when the resetting the box would resolve the volume issue. This morning I did not get any humming noise.
-The TV settings showed normal when I looked this morning before work.
I will try to see if I can get it work through TV rather than cable to resolve the issue as suggested. I will alos try the menu suggestions
I may also switch the box with another one in my house to se if it is indeed a TV issue or a box issue.
Thank you very much for your help :)
