I have this in the .../alsa-driver-0.9.0beta12/INSTALL file:

-------------------------------------------------------------------------=
----
=20
DEVFS support
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The ALSA driver fully supports the devfs extension.
You should add lines below to your devfsd.conf file:

LOOKUP snd MODLOAD ACTION snd
REGISTER ^sound/.* PERMISSIONS root.audio 660
REGISTER ^snd/.* PERMISSIONS root.audio 660

Warning: These lines assume that you have the audio group in your system.
         Otherwise replace audio word with another group name (root for
         example).

I think this is an important module for the wavetable synthesizer...=20

Because of the 'options snd snd_cards_limit=3D2.......' line in=20
/etc/modules.conf: it's looking for a second soundcard, your first card i=
s
snd-card-0 ;)
