very little power?


Hi everyone, just installed my mcintosh mx122 and mc207 to my front projector,cable box (Fios), dvd player, cd player, etc. When I play dvds or cds the sound is strong and powerful like it should be but when I play TV I get like 1/5 th the power and sound levels. I have checked all my connections but cannot figure out why everything works but the TV portion. Any suggestions or clues to what may be going on? Any help would be greatly appreciated. Thanks in advance.

Cable box is a pain in the Arris......unfortunately comcast dumbed everything down and disabled variable digital out .   It convenient, but they got too many complaints of no sound .   Yours may not even have it.  My TV is quite a bit lower than my tuner, DAC , even phono....   I just live with it.  

Dynamic range enabled on cable , dvd, Blu-ray will sound poor on a good system.  It is to compensate for crappy systems and sound bars.
Thanks for the input, but pretty sure now I am going to have to live with it as well. I have tried everything including a different box and same results. everything is now hooked up through HDMI and I have the box set on pass through. It helps a tiny bit but not much. Guess I am going to just have to give up watching TV. LOL
I have the arris 1100vms I think t is  with Verizon,  if you press the D button which I think is the green one when the cable box is turned off and keep pressing it while you turn the set top box back on it brings you into the setup menu which has all of  the Settings you do not have access to on the normal menu. I think it is for integrators not the average joe.  Try that and see if that helps.
