1921The ALSA driver fully supports the devfs extension.
1922You should add lines below to your devfsd.conf file:
1923
1924LOOKUP snd MODLOAD ACTION snd
1925REGISTER ^sound/.* PERMISSIONS root.audio 660
1926REGISTER ^snd/.* PERMISSIONS root.audio 660

1928Warning: These lines assume that you have the audio group in your system.
1929 Otherwise replace audio word with another group name (root for
1930 example).
