Thread: Sound devices have all turned gray except Dummy Device 12.10 64bit

i had realteak motherboard sound , usb gamecon 780 sound working fine. booted , they're grayed out , have "dummy output".
history, installed kubuntu 12.10 onto 120gb partition (/deb/sdb5) w/ 8gb swap (/dev/sdb6). got ssd, share swap partition boot ssd anyway (tho getting errors mounting swap @ times, that's separate issue) run windows gave 10gb kubuntu. not enough, discovered --bind option mount, here's fstab:

# /etc/fstab: static file system information.
#
# use 'blkid' print universally unique identifier a
# device; may used uuid= more robust way name devices
# works if disks added , removed. see fstab(5).

i'm going put info here possible can me:

mounts working, had reinstall bunch of stuff it's been working grand week now. left home var , tmp on ssd. odd glitch picked hdmi output default when rebooted, , every , i'd message kde 2 dozen lines saying
hda alc888 (or similar)
no longer detected, remove? hit no.

wanted more control installed pavuctontrol, pain in butt dependencies, allowed me force off hdmi good. movies, music, games, until tonight when boot , see dummy device sound device , none of sound modules loading anymore!

sooooo
don't can load "snd" , "snd-hda-intel" module using sudo modprobe command line, loads dependencies, , voila onboard sound works (it doesn't work if snd, have snd-hda-intel also) alsamixer, pavucontrol, movies, works fine. can load snd-usb-audio , headphones work too.

said worked fine week or two. it's it's not loading alsa modules or reading alsa-base.conf or something. said didn't touch alsa-base.conf except 1 line after problems started. no relevant alsaerrors in dmesg or syslog either.
wait cancel that, have in syslog:

[ 10.234258] init: alsa-restore main process (1156) terminated status 19



suppose hard code these /etc/modules, seems crude , not how it's meant done. can me troubleshoot why it's not loading snd modules?

understanding mounted configuration kind of bent head ...

think if booted system , did not custom modprobing, instead ran alsa diagnostic script, review of might reveal not happening should happen.

per https://wiki.ubuntu.com/audio/alsainfo

do:

code:

cd ~/   wget http://www.alsa-project.org/alsa-info.sh -o alsa-info.sh && bash alsa-info.sh
