no /dev/dsp nor /dev/mixer on 2.6.9

Hai...

I just upgrading my kernel from 2.6.7 to 2.6.9.
after i install alsa module (ver 1.0.6a) succesfully into 2.6.9, i run "modprobe snd-emu10k1".

and then i type lsmod. and i see that the driver is loaded. but the problem is, there's no /dev/dsp nor /dev/mixer or even /dev/sound/ block devices.

My system is Slackware 10.0
SB Live Value! (with alsa 1.0.6a).

Any clue ?

Oh btw, do we need that udev-x.x.tar.xx program when running 2.6.9 ?

Thanx...

I run Debian Unstable, but have the same problem. So... bump!

Did you enable devfs?

udev is needed if you want to dynamically create nodes in /dev when you load modules, so unless you want to make nodes manually it's good idea to have it.

I'm using Debian unstable too.

Maybe 'modprobe -v snd-pcm-oss' resolve this.

It's udev erasing and then recreating your /dev directory at every boot. This is one of the reasons why I don't like the 2.6 tree. I'm stuborn and didn't feel like learning how to correctly fix the problem. Eventually I moved back to stable but you can insert:

Code:

. /sbin/snddevices

into the very top of /etc/rc.d/rc.alsa

Then download the alsa-driver source code and move the snddevices script into /sbin.

I know, it's an ugly hack, but it works. You might consider it until you can go upstream to the source of the problem, which is UDEV.
