ALSA, kernel 2.4.24-1-686 and intel AC'97 sound card

[Chris Searle <debian@chrissearle.org>]

Have successfully got ALSA running on my -k7 with an ensoniq 1371 by
following the instructions here

http://www.linuxorbit.com/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=541&page=1

And by following the info under the "Stock Debian kernel without
precompiled modules" section. Only difference was that it was also
necessary to install alsa-base and alsa-utils - just prior to
installing the build alsa-module deb.

So - I've just tried the same on this -1-686 with

00:1f.5 Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio Controller (rev 02)

Searching alsa-project seems to imply that you need the intel8x0
driver - at least
http://www.alsa-project.org/alsa/driver-source/pci/intel8x0m.c shows
the 82180CA card although the soundcard search on the alsa pages does
not.

Built the module, installed it and rebooted.

lsmod gives for sound modules:

snd-seq-oss            29632   0 (unused)
snd-seq-midi-event      3264   0 [snd-seq-oss]

audio                  43352   0 (unused)
soundcore               3940   5 [snd audio]

And at boot time I get the messages:

intel8x0: clocking to 48000
ALSA mixer_oss.c:1224: unable to register OSS mixer device 0:0
ALSA pcm_oss.c:2376: unable to register OSS PCM device 0:0

Google for ALSA "unable to register OSS PCM" gives hits for the 2.6
kernel but not the 2.4.

Anyone got ALSA running for this sound card?
