I didn't catch the other responses to this so I'm
probably out of touch.

I think this means your hardware capabilities are
irrelevant. Just don't use hardware monitoring.
in alsamixer, look for a "Rec." toggle
on the
line-in channel. I had
this very problem with my i810 compatible
(nforce2) onboards sound.
Well, you see, therein lies my problem! I am using
the LINE IN jack for
recording (of phone line audio).
Perhaps a graphic will illustrate it better.

So I guess if I'm using the LINE IN jack on a PC for
recording, I will
always get some of that mixed into the LINE OUT
audio?
That should be wrong because a signal doesn't have to
route to alsa_pcm:playback.
In my application, I would have preferred these to
be isolated so that the
audio arriving into LINE IN would never be mixed
into the LINE OUT audio,
but I guess this can't be done.
I suspect you have the absolute correct idea but have
hit a snag. Perhaps hardware monitoring is set on.
