I'm sorry to be posting another alsa request but I have ben fighting alsa on RedHat 9.0 for a month now. I have gone through the documentation on the alsa home page and tons of others. alsa works great on my redhat 8.0 box and I had it installed in less than a day.

No one seems to give mention that on RedHat 9.0 that when you recompile your kernel to have sound module enabled "m" and the rest as no "n" as suggested. Then try to compile alsa with src rpm or just the source that your kernel-tree doesn't reflect the state of the installed kernel.

I did this.
cd /usr/src/linux-2.4.20-18.9
$ make mrproper
$ cp /boot/config-2.4.20-18.9 .config
$ make oldconfig
$ make dep
$ chmod 777 /dev/audio*
$ chmod 777 /dev/dsp*
$ chmod 777 /dev/mi*
$ chmod 777 /dev/sequencer*
$ rpm -ivh alsa-driver-0.9.4-fr2.src.rpm
$ rpmbuild -bb --define "kernel 2.4.20-18.9" --target i686
/usr/src/redhat/SPECS/alsa-driver.spec
and installed the rpms.
I repeated the process for alsa-lib and alsa-utils.
when I ran
modprobe snd-emu10k1;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss
most everything worked except 4 modules.

$ depmod
depmod: *** Unresolved symbols in /lib/modules/2.4.20-18.9/kernel/sound/snd-gus-lib.o
depmod: *** Unresolved symbols in /lib/modules/2.4.20-18.9/kernel/sound/snd-seq.o

depmod: *** Unresolved symbols in /lib/modules/2.4.20-18.9/kernel/sound/snd-vx-lib.o

My alsa mixer works and I have good sound!
Have I missed somthing with my make xconfig or a pemission?
