Ok this is my first post on here and I'm not sure if it belongs in this forum or somewhere else, if this is in the wrong place mods could you please move it to the proper spot?
I have an older RCA 2250 HTIB unit that I decided to put into my office, so I can have a bit better sound from my LCD HD TV, seeing as I spend most of my weekdays in there doing work. I hooked up my TV, HD Cable Box and PC to the receiver. I Have an HDMI cable going from the Cable Box to the TV, Monster RCA cables from the HD box to the RCA receiver.
Here is the problem, I keep getting a popping/crackling noise from my all of my speakers and it is getting really annoying. I have tried noise filters on the power line, different outlets, 2 sets of RCA Audio cables, and I even changes my speaker wire from 16 gauge to 14 just in case that was the issue. I'm not sure what else I can try, it seems to happen more frequently when I'm watching something in HD, but that might just be me.
The other issue is when I shut the RCA receiver off for a few hours and turn it back on all I get is static for the first 10 minutes or so, then it goes to a low buzzing, then silence and finally after about 10 minutes of silence I finally get sound from the TV or PC.
Any ideas?

Disconnect the PC, TV and cable. Turn it on and play the radio. Does it still perform Rice Krispies? If so, there is a problem with the unit. Especially if it still takes 10 minutes to fire up.
If not, something else is causing the issue.
Some PC's are filthy when it comes to audio grounding, and they can cause all kinds of power-related issues. Have you tried disconnecting the PC while you watch HD?
Have you tried connecting the cable box to one of the other inputs (CD or VCR in)? If so, the RCA input connector(s) could be damaged.
Does it happen with the surround turned off, set to stereo speakers only? Could be a bad surround signal from the cable box. Connect a DVD player in place of the cable box. If it works fine, the cable or HD signal itself may be the cause.

You could have the negative and positive switched on one or more speaker.

"I unhooked to PC line and Snap, Crackle and Pop stopped. Now to figure out how to ground my PC better."
Make sure the PC is plugged into the same power strip as the A/V system. If that doesn't help, there are audio transformers available that will electrically isolate the two systems.
