Channel Volume

Once again Xfinity is having issues with the volume on certain channels. I have set the volume on my television at the highest level it will go.  I have unplugged the cable and wifi, plugged everything back in and still the volume for channels ABC, CBS, NBC, etc. are barely audible at 50.  
Other channels such as ION, WGN, sometimes FOX, TLC, FF, etc the volume works just fine on 15-20 depending on other noises.  
While I have no issues with the volume on Roku, Amazon Prime, Netflix etc.  They are all audible on as low as 6. 

Anyone else having issues with Xfinity and various channel volume issues?
