Since the radio interference is purely a hardware thing, I'd say that
the Linux sound driver is configured to turn on some input that
is susceptable to the interference.
Here are two ways you can test this:
1. Run Windows and open the Volume controls (right click on the
speaker in the system tray). Make sure that inputs like line-in
and microphone are not muted and the volume is above 50% or so.
Listen for interference.
2. Run Linux, and open the mixer of your choice (either KDE or Gnome)
and check the setting of the inputs there. Adjust the inputs
and see if there is a difference in the interference level.
I'd suspect the microphone input since it's the highest gain input and
(normally) the longest input lead.
Let us know what you find out!
