Problem - Gain out of my cable box to my Processor

check your cable box setup. Mine have the ability to control volume output. You can switch the volume between variable and fixed. Chances are you have it set on variable (many come that way default) and the volume level on the box is set low. You can either switch it to fixed, or turn the volume up (though I would put on fixed as the digital volume controls can't improve fidelity).

I have Comcast and the same problem.
In the set up menu you can adjust for high compression, light compression or no compression, but no volumne level.

Most channels are ok , the ones that I have problems with are the Live Music Concerts. I really have to crank it up to get the volumne level.
I have to be careful when I change channels because of the huge sound level difference.
Calling Comcast does no good.

Same issue with Comcast and my Scientific Atlanta HD Box. I suppose you could set the volume to variable and turn it up for a particular movie/show you are watching but would suggest turning it back to fixed after that.

I have Verizon FIOS and it has both Compression as well as fixed/variable volume output. I previously had COMCAST but that was a long time ago and I don't recall what my setup options were. I believe there are devices that will level volume outputs for all channels, but I think they cost a couple hundred $s and it ticks me off the service providers won't do this w/i their systems.

Nick778, My Comcast (Motorola HD DVR box) will not allow any volume adjustments.
