/dev/dsp disappear at boot

dimarcoe · 02-04-2006, 04:38 AM

Hi all,

I have my sound device working in /dev/dsp. When I reboot my computer the device disappars and so my
sound doesn't work. What I hae to do is, after every reboot, remake the device using:

mknod -m 666 /dev/dsp c 14 3

This problem startd after a recent dist-upgrade of my debian unstable distribution.
How can I get rid of this? I don't want to add this command in the startup scripts...

Thanks,

emanuele

I don't use debian, but it sounds like after your upgrade you may be using udev. udev dynamically creates devices as needed. Try issuing modprobe snd-pcm-oss as root.

If you're using alsa and udev, and this kernel module is available in /lib/modules, then when the module loads /dev/dsp will be created dynamically. If that works you can add snd-pcm-oss to /etc/modules or /etc/modprobe.conf or whatever the module configuration file is on your system.

You can tell if your system is using udev by issuing ps -ef|grep udev and seeing if udevd is running.

Yes, ok. It worked!
Now I added this in my modules configuration.
Do you know if there is some other issue than need to be changed in the "upgrade" from hotplug -> uudev?

Thanks a lot!
