No problem, the kernel will take care of proper IRQ assignment if you compiled in support for ISAPNP. IIRC the AWE32 is a PnP card. > => Faut-il que je recompile le noyau ? avec autres options... > Merci de votre aide.... Upgrading to a new kernel certainly doesn't harm.

All ALSA programs expect the sound devices to live in /dev/snd, which is a symlink to /proc/asound/dev . On systems with a normal /dev tree such a symlink is persistent over reboots, but devfs needs more magic. You can probably solve the problem temporary by using "ln -s /dev/snd /proc/asound/dev" and restarting alsa (probably with "/etc/init.d/alsasound restart"), but I have no idea what devfs magic is needed to make this change persistent. You should consider disabling devfs completely, because it is known broken (read a linux-kernel archive for more information). Mandrake issued a securety announcement for this a couple of months ago.
