Thanks. I have tried that actually, but it didn't seem to have an effect.
Here is what I have found out so far:
1) The CD player itself is working, as I can get sound by plugging my speakers or headphones straight into the CD player jack on front
2) The TB USB card will produce some sounds (successful soundcard tests and "events" in the GNOME GUI). However. when I use CD player, the music will not come through the speakers, if plugged into the card.
3) Linux appears to be recognizing the soundcard(s) correctly, as the correct module shows under soundcard test. They just aren't actually working properly when it comes to producing sound.
4) Based on running a test I found in "Running Linux," the kernel (2.6.12) has the correct modules installed, and it should not be necessary for me to recompile it.
5) "Running Linux" indicates it could be a problem with mixer settings, as the input needs to be set to CD input. I have used the mixer installed with the card as well as the alsamixer, and have yet to figure out a way to do this. Volume is definitely on, though, and no channels are muted.
6) I do get an error when I boot up, which I think is referring to the CD RW drive I am using to play the CDs. Text below, taken from dmesg:

My theories at this point are that there is a software setting somewhere that needs to be changed, but I haven't been able to figure out where or how because...well, I'm a newb. Or, something is wrong with the CD RW drive. Running Linux talks about modifying config files, but I haven't been able to figure out where the correct ones are on my system. Bugzilla has some related topics, but I wasn't actually able to glean a fix from it.
Any help is appreciated.
