While playing DVDs especially, I notice sometimes I get crackling sounds from my speakers. I seems to happen more frequently when the sound is louder. What I am asking, is what are the probably causes of this type of thing? I have a Kenwood lower end receiver (about a year old) and a 5.1 set of Onkyo speakers, and a Sony, non progressive scan DVD player about a year old as well. My thoughts on this are that it could be any one of the following with the first 2 most likely, but I'm not sure if this is where to start: 1) Speaker wire (I wired this awhile back for a different setup, and there may be a splice or two in them) 2) Componant cable (inexpensive cable that I bought from a PC fleamarket, but I figured that for my modest system, it would probably be good enough). 3) Bad reciever 4) Bad DVD player (unlikely since this happened on a different DVD player. 5) Subwoofer setting off (I monkeyed around with this, but it didn't seem to help) I'm looking to play around with my system over the long weekend, so any help as to where to start would be appreciated.
