[linux-audio-user] No state is present for card

[Denis de Leeuw Duarte]

Well I fixed the access problem quite easily last night actually. This might 
be a bit distro dependent since not all of them use the devfs, so ymmv. In 
/etc/devfsd.conf add this:

LOOKUP          snd          MODLOAD ACTION snd
LOOKUP          dsp          MODLOAD
LOOKUP          mixer        MODLOAD
LOOKUP          midi         MODLOAD
REGISTER        sound/.*     PERMISSIONS root.audio 660
REGISTER        snd/.*       PERMISSIONS root.audio 660

Which then gives access to the audio group automatically. Add yourself to 
the audio group and you're done. It didn't seem to work with me at first, 
but I just had to log out of my kde session an login again and then it 
worked.
