And adding here that CD in is just one of two analog in paths I use that
I don't want to do digital data transfer on.  You didn't address the
other one.

Depends on wether or not the drive has an analog out.  Most don't, but
I've seen them in the past that do.

As mentioned in my previous mail, my most recent motherboard purchase
does, and so did all my previous purchases.

Well, duh.  I don't *want* that junk.  I want a zero intervention pass
through that leaves my system unoccupied by mundane, trivial crap. Oh,
and my sound card automatically plays 2 channel stereo line in as either
4.1 or 5.1 output, so I *really* don't want CPU based surround upmixing.

I *know* it's connected, I connected it myself.

And this has nothing to do with whether or not the mixer should be able
to deal with analog in to analog out directly, which was my complaint.
The CD portion of it was just one instance, the other being my use of
line in for my iPhone.  Assuming that because you don't have access to a
CD player that does CDDA based playing today means that it simply
doesn't work in the hardware is just silly.  And assuming that because
your CD in path doesn't work that no analog input path should be
redirected in hardware to speakers is also just as silly.
