Say, that sounds familiar....
I used to have a system where that would happen. It turned out to be
stray noise from unused inputs. I found that turning down one of the
mixer settings (can't remember which one) fixed the problem.

That also sounds like a mixer issue. If you set the line-in volume up,
it goes to the output in hardware - regardless of what software is
running. You should have separate controls in the mixer for line-in and
capture volume. You want to set the line-in controls all the way down,
and the capture volume to whatever's reasonable. (on my system, that
turns out to be surprisingly low, around 35%, otherwise it distorts).
