crackling noise. goes away when volume is upped

I have this issue that sometimes the volume starts crackling up and disappearing. It could always be rectified by raising the volume (it reappears solidly) and then lowering it to a normal level again or by changing a channel and going back. This happens in the TV mode only and I am wondering whether to blame a cable box (though it happened with a cablevision's one and is now happening with verizon's one as well), the amp (Sherbourn 5/1500A) or the pre-amp (Denon AVP-8000).

thanks much

I experience the same problem with my 2.1 video set up.
I run DirecTV digital out to a MD10 virtual surround DAC/PRO decoder.
One channel will disappear and come back if I raise the volume a little.
I use the analog pass through on a Parasound AVC 1800 for the Left - Right - Sub output of the MD10.
My next step is to lower the level controls on the Parasound amps in order to raise the volume level higher on the pre/pro and see if this solves the issue.
