Sound fix in 12.10
Sometimes after booting up Ubuntu 12.10 or Quantal sound system dies when you you access the sound in System Setting -> Sound the driver shows as Dummy no Output driver. The fix is simple you can either open a terminal and type:
--( >:-))-#-> sudo alsa force-reload
or
su as root then type:
--( >:-))-#-> alsa force-reload
That's the fix.
