I'm changing the component to MAKEDEV but that may not be the right
component.  I don't know why /dev/dsp wouldn't exist.

Comment 3 Nalin Dahyabhai 2004-04-15 07:51:10 UTC
IIRC "No such device" means that the device node is there, but there's
no device driver attached to it.  I don't see a hardware-specific
driver in the list of loaded modules (on my test system, both
snd_emu10k1 and snd_ac97_codec are also loaded).

Please attach the contents of /etc/modprobe.conf and
/etc/sysconfig/hwconf so that we can get a better idea of what's going
on and what's supposed to be going on.  Thanks!

more /etc/modprobe.conf

/sbin/modprobe -r --ignore-remove snd-es1960

Comment 5 yvan turmel 2004-04-15 18:22:34 UTC
merci .
maintenant ca fonctionne.
j'ai d'abord supprimé dans hwconf class:AUDIO
puis dans modprobe.conf j'ai ajouté alias snd-es1960 snd-es1968

ensuite reboot
puis detection de kudzu
et ca marche ???.

probablement que lors de l'installation initial il y a eu une 
mauvaise detection.
