I have an ASUS P4P800 Deluxe/Intel P4/865PE Chipset and an AD1985 Analog Devices sound chip. It uses the AC97 codec. I have tried ALSA and their guide for the AD1985, but it seems to fail on Fedora Core 1. (kernel 2.4.22-1.2115.nptl) It has worked for me before on Mandrake Linux 9 and 10..
I have tried three versions of ALSA( 0.94, 1.03, 1.05 ), all miserably failing with the same messages. This is configured without the alsa OSS and sequencer. If I ./configure with the sequencer, i get errors about the sequencer..so I thought turning it off in configure might help, but apparently not. Both turned off I still get these error messages:

i have a different soundcard, SiS 7012, but same sort of problem, it refuses to load the modules =/

Well, unresolved symbols means the file is accessing external symbols but can't find them. You can try doing a

depmod -a

then modprobe it again, or as I do it myself, the manual way:

cd /lib/modules/[kernel-version]/kernel/sound
for i in `find . -type f`; do grep -l $symbol $i; done

Replace $symbol for the unresolved symbols, lika for example snd_device_new_R747d564a. It looks like you don't have the soundcore module loaded, though, but I'm not sure.

Oh, and if you find the symbols in a module called, say, modulexx.o, but upon

insmod modulexx

you get

/lib/modules/[kernel-version]/kernel/sound/modulexx.o: unresolved symbol snd_some_symbol_here_1234567

Then repeat the search with the symbol snd_some_symbol_here_1234567, and so on until you have loaded all the modules. Just like recursing

And keep your progress, preferably on a notebook, so that when you have succesfully loaded all the modules, you can insert the dependency into /etc/modules.conf (read the man page)

wpyh, thanks a lot!

I now have my snd-intel8x0 driver loaded.

Excellent, excellent!

Thank you so much. Hopefully I can use this for other 'unresolved symbols' as well.
One question: Do I have to insert these commands in /lib/modules.conf?

Current /lib/modules.conf:
alias usb-controller usb-uhci
alias usb-controller1 ehci-hcd
alias ieee1394-controller ohci1394
alias eth0 sk98lin
alias sound-slot-0 snd-intel8x0
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

# and would I insert ALL of those insmod commands right here? or just modprobe snd-intel8x0?

I will also test the audio to make sure it works, if it doesnt, I'm probably doing something wrong. I'll report my findings here.

Oh.. and one more thing yet: do you know any easy way to restart ALSA (or to avoid those "/dev/dsp device in use" messages when an audio application crashes)?

Thanks again.
