Chris,
Yes, they do. It's called a "Ground Loop Isolator," and it works pretty
well. It's a
transformer (two, really), male RCA plugs in, male RCA out. It isolates
the source from the
load, so no ground currents flow. I had one many years ago, and found it
has remarkably
wide frequency response, and doesn't saturate and distort the bass,
unless, of course, the
signal levels get too high. I don't know if it works will with
high-frequency ground noise
though, as with a computer -- if it has a lot of internal cross-winding
capacitance, it
might not be as effective.
Searching Radio Shack's site with "Audio Isolator" found a different page,
with a different
photo, than did searching for "Ground Loop Isolator." Go figure. Same
part number.
Another thing that worked in one situation, was to not connect the ****elds
of the cable to
the plug plugged into the audio out jack of the computer, but to connect
them directly to
the chassis of the computer. SOunds totally non-intuitive, the kind of
thing you WOULDN'T
ever want to do. But it got rid of the noise. That's a bit of a crap
shoot, though -- your
case might be different. Easy enough to try.

Thanks a lot..
