I did this and rebooted, but I still have no sound devices:


$ ls /dev/snd
ls: /dev/snd: No such file or directory


$ lsmod | grep snd

$ cat /etc/modules | grep snd

After running dpkg-reconfigure alsa-base, I get:

$ ls /dev/snd
controlC0  hwC3D1    midiC1D6  midiC3D7  pcmC1D0c  pcmC2D0p  pcmC3D1c

I can then run:

$ /etc/init.d/alsa-utils start 

which restores my mixer settings and I can use my sound applications
again.

For some reason /dev/snd/* is not being created. Perhaps this could be a
problem with udev?
