This happens every so often, about 3 days ago I put Nick on and the commercials had no sound to it? This confused me cuz all the other channels have sound. I am not sure if it is helpful but I have an Insignia tv, not sure what the actual details are. But if anyone knows any possible fixes that would be greatly appreciated since Nick is my main channel I watch at night.
I have Comcast and the box is one of those digital converter box things. Dunno if that helps either, but I dont know if it has something to do with Comcast or my tv...cuz the commercials have sound on the other tv's in the house as well.
