Problem - Gain out of my cable box to my Processor


I'm connecting my Cable Box to a surround processor (Meridian 565) using an optical cable. The sound is very low, I have to really crank it to hear. Tried using a digital cable and have the same issue. The sound is normal if I use either of the same connections coming from my bluray. Anybody had this experience? WHAT TO DO?

Thanks

Nick778, My Comcast (Motorola HD DVR box) will not allow any volume adjustments.
The 565 if I remember correctly has input sensivity ajustment from 1 volt to 3 volts for every input indepently. It should be in the manual.
Thank you all for your thoughts. I did change the volume output to fixed on the Comcast (Samsung) box. Meridian does allow you to adjusts your inputs via a gain adjustment to make them all approximately the same, but this only works on the analog inputs, not on the digital or optical.
I will look into the compression adjustment, that is a new one for me.
Strangely I have to put the volume up over 3/4 on a 200 watt amp to get a barley decent sound level on regular TV.
Maybe newer equipment is set up to accommodate this?
