humming noise

[[email protected]]

I have a long RCA cable from my PC to my receiver. The sound has a
loud hum in the background. Is it just a sorry integrated audio
problem, cheap cable or something else? Thanks for input. I don't
hear the hum on my PC speakers. Maybe it is just real low there?

My money is on a ground loop. A transformer isolation cable from
radio shack will address that problem. Or, plugging the pc into the
same circuit/outlet as the receiver.

Also, might check if the problem goes away when you disconnecte cable
TV from your receiver/tv system. Co-ax from the cable company is not
uncommonly associated with ground loop current.

Try another interconnect. If you didn't have "hum" before, it most likely you're most recent change....and I have no idea what that might have been.
