Andrew,
I have mentioned earlier, there's seems to be some kind of ALSA, udev
or sysfs issue with /dev/dsp and friends not being created under
recent mm kernels.
Last kernel that worked; 2.6.10-rc1 and i belive 2.6.9-mm1. 2.6.10-rc2
and mm3 have issues.
The odd thing is that my log shows /dev/dsp /dev/mixer being setup by
udev upon startup.
I run nForce2 based board with soundstorm audio by way of snd_intel8x0 module.

I use the latest version of udev-046. Is there anything else i can do
to try to debug this? as i see no errors other than /dev/dsp no such
sound device. Playing oggs works OK though when using ALSA.

It's trying to create nodes under /dev/sound/

But your /dev/sound appears to be a character device node, not a directory.
Did you try rm /dev/sound, mkdir /dev/sound?

Ok, i tried removing /dev/sound char device then making /dev/sound
directory and upon reboot the directory becomes the char device again.
Still no /dev/dsp.
Here is what i have noticed when running the udev startup script
/etc/rc.d/rc.udev on slackware:
When run after startup and udevd is already running it will create the
/dev/sound and friends and symlinks to dsp,mixer,audio under /dev eg.
--> ls -l /dev/sound
total 0
crw-rw--w- 1 root audio 14, 12 2004-11-27 21:13 adsp
crw-rw--w- 1 root audio 14, 4 2004-11-27 21:13 audio
crw-rw--w- 1 root audio 14, 3 2004-11-27 21:13 dsp
crw-rw--w- 1 root audio 14, 0 2004-11-27 21:13 mixer
and
--> ls -l /dev/{dsp,audio,mixer}
lrwxrwxrwx 1 root root 11 2004-11-27 21:13 /dev/audio -> sound/audio
lrwxrwxrwx 1 root root 9 2004-11-27 21:13 /dev/dsp -> sound/dsp
lrwxrwxrwx 1 root root 11 2004-11-27 21:13 /dev/mixer -> sound/mixer
but since /proc must be mounted before udev is run then invoking udev
for the second time breaks /proc's permissions thus this happens:
--> ut2004
libGL error: failed to open DRM: Operation not permitted
and dmesg prints:
