Well ..... hmmmm.

That's kindof odd, because the lsmod output below shows that the modules
do get loaded, and those names are only an alias for the actual module.
I use Slackware though, which doesn't use the modules.conf file, so I'm a
bit rusty on this.

You might want to comment out that section of your modules.conf, reboot,
and then load each module by hand and check for informational messages.
This output:

Makes me want to think that everything is okay, because everything seems
to be used. (except snd-seq-oss).  I'm not a real genius when it comes to
modules, though.

Other than that, I'd grep "snd" around in the logs and see if there are
any complaints.  Really though, it sure sounds like a mixer issue.  Is
there a way to verbosify the output of the alsa mixer?  Anyone else got
other ideas?

The other thing I'd do is post this stuff to the alsa mailing lists.
