	This is weird as I am running the same version of ALSA for
the intel8x0 audio card on my Toshiba laptop... One question I woudl ask
is if your alsa-{source,base}.conf files are correct and list the proper
card... in alsa-source.conf I have ALSA_CARDS="intel8x0" now as to my
devfs setup check below...

	The only devfsd configuration info I have relating to ALSA is
as follows:

In /etc/devfs/perms:
REGISTER ^sndstat PERMISSIONS root.audio 0660
REGISTER ^sound/.* PERMISSIONS root.audio 0660

In /etc/devfs/compat_symlinks:
REGISTER ^sound/.* MKOLDCOMPAT
UNREGISTER ^sound/.* RMOLDCOMPAT

In /etc/modutils if I run 'egrep "s(ou)?nd" *' it returns:

1devfsd:alias     /dev/sound            sound-slot-0
1devfsd:alias     /dev/audio            /dev/sound
1devfsd:alias     /dev/mixer            /dev/sound
1devfsd:alias     /dev/dsp              /dev/sound
1devfsd:alias     /dev/dspW             /dev/sound
1devfsd:alias     /dev/midi             /dev/sound
alsa:alias char-major-116 snd
alsa:alias snd-card-0 snd-card-intel8x0
alsa:alias char-major-14 soundcore
alsa:alias sound-slot-0 snd-card-0
alsa:alias sound-service-0-0 snd-mixer-oss
alsa:alias sound-service-0-1 snd-seq-oss
alsa:alias sound-service-0-3 snd-pcm-oss
alsa:alias sound-service-0-8 snd-seq-oss
alsa:alias sound-service-0-12 snd-pcm-oss
alsa:options snd snd_major=116 snd_cards_limit=1 snd_device_mode=0660 
	snd_device_gid=29 snd_device_uid=0 alsa:options snd-card-intel8x0
	snd_index=0 snd_id=CARD_0

	This setup works perfectly on my system... If you have any
other specific questions feel free to contact me directly...
