LakeOntario,

Have you tried adjusting the audio output in the game console? It's not always the television that produces a crackling sound.

Turn off the 5.1 channel setup in the ps3 audio setup and it will usually fix the problem. I have my own theories of what is causing it (since I can't back it up, I won't post it), but to say that "Samsung knows" isn't necessarily the case.
