Hello--

I seem to be missing a number of device files: dsp, dsp1, mixer, mixer1, audio, audio1, and sequencer. I've tried using /sbin/MAKEDEV (after making sure it had the appropriate information), but it doesn't recreate the files. Nor does rebooting. I've tried extracting them from a stage2 tarball, but that doesn't work, either--reported success, but when I check for the nodes, they're missing. I'd try mknod, but I don't know the appropriate minor numbers (the major numbers appear to correspond to /usr/src/linux/Documentation/devices.txt).

This is really strange. Anyone have any ideas as to what it could be or what else I could check for? Or where I could find the minor numbers, at least?

I retrieved a copy of MAKEDEV from a stage tarball. Now at least I have device files.

If you are running devfs or udev, you shouldn't need to create any device nodes manually.

Normally, the device nodes will appear in /dev after the apropriate kernel modules have been loaded (i.e. the ones for your soundcard).

Try this to see if the modules are loaded for you.
Code:
# /etc/init.d/alsasound start

Thanks--the files are there, now that I've run MAKEDEV.

I'm using udev; don't know why it didn't pick up on that. Probably I didn't have it running.
