I am trying to install the ALSA 1.0.1 drivers.
I have tried the following instructions so far,

./configure --with-card=au8830
make
make install
modprobe snd-au8830

The make install part gives a bunch of unresolved symbol errors:

depmod: *** Unresolved symbols in /lib/modules/2.4.16/misc/snd-ac97-codec.o

The modprobe step can't find the module.

Any ideas what could be wrong?

did you install the alsa-library and oss-compat-library? maybe you need them as well.
