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.

This topic is from 2004, something's telling me they are not going to reply any time soon.

Hi,

Yes, it's sad that a lot of old posts are being resurrected. The 'udev' of today is much improved in the last five years.
