Oh, I was going to mention something else on that, and forgot,
since I was eager to get to my kernel 2.6 post..

By my understanding, most if not all CD/DVD players route the sound to
TWO locations via hardware, their own headphone jack, and the sound cable
that can plug in, along with the data cable, to the back of the unit.  To
my knowledge, it routes to both at once, without software control at that
level of an either/or, since it simply sends the analog audio signal to
both.

Thus, I don't think your description of the problem is entirely accurate,
since it routes to both, automatically.  Pardon me if this seems
simplistic to you, but I'd call this the most likely problem, given
what you mentioned.  Verify that you have the audio cable (NOT the
data cable, this is separate, and much smaller) connected both to the
sound card/mobo CD or AUX audio jack, AND to the similar connector on the
CD/DVD unit itself. If you don't, that's the problem. (The cable is small,
MUCH smaller than the normal ATA/ATAPI data ribbon, typically black or
gray, the jacks only four-conductor, smaller than the power jack, about
twice the size of the headphone jack, but rectangular.)

That's been my problem a few times, after I've worked on my hardware. 
I've disconnected the CD audio cable for whatever reason myself, and
forgotten to reconnect it, on occasion.  Thus, it won't be the FIRST time
that's tripped someone up.

If THAT's connected correctly, perhaps you are using the wrong
mixer app slider for the CD control, or its muted.  Verify its not muted,
and try some of the other sliders, including aux, line-in, etc.  Sometimes
they get mislabeled as the board manufacturer routed the inputs
differently than the audio-chip manufacturer intended, or than was the
case on the unit the driver developer used.  Here, I was without audio on
my new system all together, until I figured out that the master slider and
mute didn't appear to do anything, but the headphone slider and mute
worked as master!

If THAT isn't the problem, perhaps this is.  As I mentioned, that audio
cable is a simple analog audio output from the CD/DVD player.   Thus, to
the mixer, it's basically like any other line-in analog audio input,
except that this one happens to be from the CD, not from something plugged
into the external audio line-in jack.  Perhaps your mixer, or the driver,
is not functional for ANY analog line-in type applications.  Plug an
external device into the external line-in and verify that it's working, if
you haven't already.  If it is, worst case scenario, you can always run a
"loopback" patch cable from the CD/DVD player headphone jack, back around
to the external line-in audio jack.  Or.. there may be another input on
your card/mobo, for an aux-in connection, possibly with its own slider,
possibly on the same one as the external line-in.

Hopefully SOMETHING there fixes it for you.  My bet is still on that
little audio cable, tho, as it's easy to miss, and the issue can be
confusing if it hasn't happened to you b4, because as you described, the
data cable works fine, so data disks and ripping the CD data works as well.
