Bud,
Depending on your soundcard you should be able to turn
off the "monitoring" so you don't need to change the
Line In level. For example, with the SoundBlaster
Audigy 2ZS, open the "Recording Control" (input mixer),
click the "Advanced" button on the Analog Mix input and
select "Record without Monitoring." Some Realtek chips
include the inputs on the output (speaker) mixer but
they are generally hidden (select Options | Properties
and show all of the unchecked controls). You can unhide
them and make sure the Line In (it may be shown as a
"color") is muted.
