Speakers cracking noise

[pwmcon1]

Hi,
I recently installed a new Panny 42" HD plasma. I already had a new Denon 3803 Receiver. I am running Polk CS350, FX surrounds, a Delodyne sub, and my 2 mains are Klipschs. I also have some Polks LSi9's hooked up in another room.

I hear the cracking noises, randomly from the 5 speakers, plus the 2 remote speakers. I only hear these noises during TV broadcast as the source. I can listen to DVD(Denon), or cd's or FM no problems.
The noises can be as often as every few seconds.
I have Comcast digital cable in Arlington VA, the tech even installed a repeater as I live in a high rise building at the end of the hallway to improve reception.
The picture is perfect clear. My old TV was a Sony XBR trinitron, 32". I never heard these cracking noises before.

Any suggestions???

Also when had the old setup, before HD plasma I had a same speaker hookup, but now I get on the display of my Denon 3803 7 channel stereo, where before I had 5 channel. I don't know why Im getting 7 channel, as I don't have a rear center speakers
in my main room, Any ideas why this is.

Thanks for your help in advance

Sounds like you have some r e a l l y nice equipment there. I don't have any idea what could be causing that noise. Surely out of all these guys someone has experienced this before? or has an idea?

oh well....have a nice day anyway:D

PnP,
Thread is a month old... but good on ya for seeing a cry that appeared to go unanswered.

pwmcon1 also posted over in Basic Wiring (http://clubpolk.polkaudio.com/forum/showthread.php?s=&threadid=21804) and received some help.

It'd be nice if he'd let the responders know if they helped...

yes it seemed to go away
, maybe it was I changed the audio cables from what Comcast gave me to Optical.
however I still am having problems which I started another thread about

thanks
