Re: Noise in audio line out

You have what is known as "ground loop" hum. A ground loop in your
situation occurs when you hook up a computer's sound output to a separate
stereo system. The two systems are plugged into different outlets and have
an existing small ground voltage difference between them. This voltage
difference causes the Hum.
The only solution is to buy, from a good audio dealer, a ground isolation
transformer and have the dealer tell you where to install the transformer in
your wiring.
I had the same problem, and cured it this way, as others have.
