ALSA 1.0.15 having trouble loading module; can't find snd-ac97*


Hey Everyone,
Trying to get the sound running on this new laptop...running Slack 12, my soundcard is an Intel 82801H (ICH8 Family), and ALSA claims to support it in version 1.0.15 with module snd-intel8x0. So, I downloaded and installed the drivers, utils, and libs for that version, installed, ran alsaconf and everthing seemed hunky doory until I tried to load the module (via modprobe snd-intel8x0):

Code:
WARNING: Error inserting snd_ac97_codec (/lib/modules/2.6.21.5-smp/kernel/sound/pci/ac97/snd-ac97-codec.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting snd_intel8x0 (/lib/modules/2.6.21.5-smp/kernel/sound/pci/snd-intel8x0.ko): Unknown symbol in module, or unknown parameter (see dmesg)
Looking at dmesg (well, the part that seems relavent to me)
Code:
snd_ac97_codec: Unknown symbol snd_verbose_printk
snd_ac97_codec: Unknown symbol snd_ctl_boolean_mono_info
snd_intel8x0: Unknown symbol snd_ac97_pcm_close
snd_intel8x0: Unknown symbol snd_ac97_resume
snd_intel8x0: Unknown symbol snd_ac97_pcm_open
snd_intel8x0: Unknown symbol snd_ac97_set_rate
snd_intel8x0: Unknown symbol snd_ac97_update_bits
snd_intel8x0: Unknown symbol snd_ac97_mixer
snd_intel8x0: Unknown symbol snd_ac97_bus
snd_intel8x0: Unknown symbol snd_verbose_printk
snd_intel8x0: Unknown symbol snd_ac97_pcm_double_rate_rules
snd_intel8x0: Unknown symbol snd_ac97_update_power
snd_intel8x0: Unknown symbol snd_ac97_suspend
snd_intel8x0: Unknown symbol snd_ac97_get_short_name
snd_intel8x0: Unknown symbol snd_ac97_pcm_assign
snd_intel8x0: Unknown symbol snd_ac97_tune_hardware
I'm a semi-newbie but it seems like this snd_ac97 stuff is not included in the kernel I am currently running. Does that mean I have to get a completely new version of the kernel? Is this a kernel problem or an ALSA problem?

Thanks a bunch!

in the termenal type alsaconf. let it set it up then if it keeps trying to load the incorect module then it is time to recompile a new alsa modules for it those modules are already in your kernel did you just install that kernel from a package or did you compile it. That looks like slackware 12.00 kernel. and I have had problems with the default install of both kernels. not even though you have two sets of modules they both are linked to the same source. try booting the none smp kernel. see what happens. but as usual i re compile for my computer all my kernels.

Thanks for the reply, I'm actually having a slightly different problem now, but I think I'd like to try playing with the kernel anyway (The new problem is that I don't get error messages when I load snd-intel8x0, but I get no sound. It's not a permissions issue, since it doesn't work for either root or user). So, I'd like to try this, but I don't really understand what you mean. I downloaded the Alsa files, untared and installed them, I didn't do a kernel recompile. I suppose what I don't get is that when I look in the .config file for my kernel, I only see two possible options relating to ALSA (this was just searching for "ALSA"):

CONFIG_VIDEO_SAA7134_ALSA=m
CONFIG_VIDEO_CX88_ALSA=m

So when you say "then it is time to recompile a new alsa modules for it those modules are already in your kernel", I don't see how I could enable these options in my kernel.

Thanks very much for your help; I have some experience recompiling kernels, but I am essentially using the default with only a few options enabled to deal with my wireless connection.
