A passive DI-box with ground-lift will to the trick. The problem here
is not the asymmetrical signal since the noise is not inducted to the
wire. It's that any computer introduces quite a lot of buzz and hiss to
the ground wire. You can easily hear when the cursor moves or when data
is read from hard-disc and so on.

Best, Dennis
