/dev/dsp ... it goes away after a reboot..


Recently I've been having problems, getting sounds to play on games...mainly with cedega. I know it doesn't work well with I disabled the arts system and still no sound. Soooo..I went into /dev/ to check permissions on /dev/dsp..and noticed it wasn't there. I downloaded the source for alsa-drivers...and ran the ./snddevices script. This created the /dev/dsp file...and when i disabled arts, the sounds work (very nicely). Yet...when I reboot.../dev/dsp is gone and I have this issue all over again.

I have an audigy ls sound card, which is supported by alsa 1.0.8 (ca0106 driver)..and I'm on mandrake 10.1 official.

Help apreciated, thanks.

Since Slack 10 uses udev, the problem is probably that udev does not know to create the dsp device on bootup (with udev, device files are created dynamically). You should probably add something to your udev rules to create the device. Also, make sure that all necessary kernel modules for the device are loaded at boot time.

Do you have an /etc/resmgr.conf file? I don't have slackware, but perhaps this part is similar.
My /etc/resmgr.conf file starts with these lines:
# This is the default set of devices people logged in on the desktop get
# access to:
class desktop
# Standard multimedia devices
add /dev/audio desktop
add /dev/mixer desktop
add /dev/dsp desktop
add /dev/sequencer desktop
add /dev/video desktop
# Modem device
add /dev/modem desktop

I also have the files

If you also have these files, then it's the resmgrd daemon that creates the /dev/dsp device file.
