Nothing to fix. This is how devfs device cloning works.
Nothing to fix? The sound card that is correctly detected by the
kernel
module is not being created in /dev, ONLY after he had a power
outage. It is
not even coming back when he reboots the machine.
I don't have any suggestions, I just don't believe "Nothing to fix"
is the
right answer.
Sigh,
AFAIK dev cloning works by creating the device nodes when open()ed.
Using 'ls /dev/dsp*' will not open() any devices, so nothing is
created.
He should use 'ls /dev/dsp0 /dev/dsp0.0' and then the devices should
appear.
Try it for yourself, do 'ls /dev/dsp*' then 'ls /dev/dsp.8'
Not that anything usefull can be done with ls(1) to get sound :)

It is better to remain silent and be thought a fool,
than to speak, and remove all doubt.
I just booted up my desktop machine at home, I don't have sound
enabled by default, so I loaded the module that is required. Before
the module was loaded:
ls -lah /dev/dsp*
ls: No match.
After the module was loaded (I just load snd_driver). Nothing else was
executed after the module was loaded.
ls -lah /dev/dsp*
