hi, i have a strange problem on a new laptop, where with the alsa device directory
mysteriously disappears on reboot. this has happened to me before on another dell
laptop. this is a fresh install of debian unstable. i never got to the bottom of
exactly the same problem on a machine many months ago as i was forced to reinstall,
and that fixed it anyway.
i built a 2.4.20 kernel to allow me to use the usb-midi device. naturally i had to
make the alsa drivers again so i ran
the './configure --with-cards=maestro3,usb-audio --with-sequencer=yes --with-oss=yes
&& make && make install'. this of course went through fine as it always has.
however i forgot to run the ./snddevices script and rebooted. after reboot i realised
the error and ran the script. i edited my /etc/modules.conf and restarted the machine
another time to test the drivers. the /dev/snd directory had mysteriously vanished. i
ran the script again and had perfectly working drivers, midi and all [i have setup
alsa many times on several systems]. however on reboot, the /dev/snd directory
disappears again and again, forcing me to manually run the script. i have three other
alsa machines, all of which run alsa normally.
if anyone has and ideas as to this weirdness let me know by replying direct as i'm
sick of running the damn script on restart!
i guess i can manually make the symlinks, but i want to understand what's going on
first..
cheers,
julian oliver
a bit about the machine:
i am *not* running devfs. my filesystem is static only. this is a fresh machine
//-->
dropWorld:/home/delire# mount
/dev/hda8 on / type ext2 (rw,errors=remount-ro)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
none on /proc/bus/usb type usbdevfs (rw)
/dev/hda5 on /mnt type vfat (rw,uid=1000)
//<--
after realising i have no /dev/snd directory, i naturally looked in /proc/asound/dev.
it turns out that nothing is linked to them at all however.
//-->
dropWorld:/home/delire# ls /proc/asound/dev/
controlC0 controlC1 midiC1D0 pcmC0D0c pcmC0D0p seq timer
//<--
they are all there, so what is erasing the symlinks?
dmesg gives no clues at all, the only reference to 'snd' being for 'usb-audio'
here are my running devices after reboot:
//-->
dropWorld:/home/delire# cat /proc/devices
Character devices:

here are my init scripts:
