Yes, I've also tried playing a WAV file using aplay.  Prior to the point
when I uninstalled the alsa-kernel package for 2.4.21, I *was* able to
play a sound using aplay when I booted with the 2.4.21 kernel.

I wanted to rebuild the alsa and alsa-kernel packages, to see if that
would help.  I did an "apt-get source alsa-driver" and then tried
"rpmbuild --rebuild" on that, and then tried to install the resulting
alsa-kernel package; I got this:

# rpm -ivh alsa-kernel-2.4.23-1.ll.rhfc1.ccrma-1.0.0-1.rc1.cvs.i386.rpm
error: Failed dependencies:
        kernel-version-i386 = 2.4.23-1.ll.rhfc1.ccrma is needed by
alsa-kernel-2.4.23-1.ll.rhfc1.ccrma-1.0.0-1.rc1.cvs

Maybe I am missing some package or have the wrong version.  When I tried
that command you gave, I got:

# rpm -q --qf "%{ARCH}\n" kernel_package
package kernel_package is not installed

So, do I need to do something special to be sure I have the right
package?  Is there something in addition to "apt-get install
planetccrma-core" that is required?

Before I go to alsa-devel, do you know of anything else I can do to see
if sound is being "sent" wherever it's supposed to go?  Can I look at
something in /proc, for instance?  I tried ecasignalview, and it shows a
meter moving as if there's sound when I play a wav file.  But, of
course, no sound.
