no /dev/dsp after udev upgrade

bluePoet · 2006-02-11 18:01:29

Hi there,

I did an upgrade to udev 0.84.3 and now I dont have /dev/dsp anymore. Xmms with alsa and alsamixer works fine, but I still need /dev/dsp for Skype or X-lite and the GKrellm-Volume-Plugin.

ok, what I already did:

I removed the OSS compatibility modules from modprobe.conf,

I tried to use the new udev.rules that came with the package, after that no soundcards were found and my Trackball was disabled, also my 00.rules didnt work anymore,

I checked the sound section in udev.rules with my last config, no difference switched back to the old udev config, and there I'm stuck without /dev/dsp

It's a simple notebook onboard chip and Arch is up to date.

thanks in advance for any help,
Christian

simple question:
have you added MOD_AUTOLOAD="yes" to rc.conf?

benoitc · 2006-02-12 10:29:09

I had two card in my computer ;intel8x0 chipstet that come in the motherboard and sb live emu10k1 chipset. After reboot I had no sound. I edited modprobe.conf to enable snd-emu10k1 at first card, maybe this is your problem too :

alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-intel8x0

options snd-emu10k1 index=0
options snd-intel8x0 index=1

alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1

And thanks to iphitus to give me the trick

damn, stupid me
yes, I added the MOD_AUTOLOAD="yes" to rc.conf, but it seems that the snd_intel8x0 module didn't load so I added it to the Modules array and everything is ok now,
I should have checked this first, maybe next time

thanks for your help

I had a similar problem with printing. For some odd reason, the "parport_pc" module is no longer being loaded even though MOD_AUTOLOAD="yes" is set in the rc.conf file.

Printing stopped working after the most recent upgrade of the kernel and udev.

The quick fix was to add "parport_pc" to the list of MODULES in rc.conf.

I have a similar issue. MOD_AUTOLOAD is set to yes, my sound module (snd_cs46xx) appears with lsmod, sound plays in alsa applications, but no /dev/dsp and hence no sound in Doom3.

Any idea where I can start looking?

Have you removed OSS compatibility entries from /etc/modprobe.conf?

Snowman · 2006-02-26 22:33:28

Is snd_pcm_oss loaded?

Having same problem.

Yes.

# lsmod | grep pcm_oss
snd_pcm_oss            50848  0
snd_mixer_oss          17920  1 snd_pcm_oss
snd_pcm                84100  3 snd_pcm_oss,snd_emu10k1,snd_ac97_codec

#

Good or bad?

I have this in /etc/modprobe.conf:

#

#
# /etc/modprobe.conf (for v2.6 kernels)
#

# OSS Compatibility
#install snd-pcm modprobe -i snd-pcm ; modprobe snd-pcm-oss ; true
#install snd-seq modprobe -i snd-seq ; modprobe snd-seq-oss ; true

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.10 ---
alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
# --- END: Generated by ALSACONF, do not edit. ---

Removing the compatibility entries from /etc/modprobe.conf didn't do anything. But:

Nope, that wasn't loaded. Added it to the MODULES section in rc.conf, everything is working now. Thanks!

Snowman · 2006-02-27 21:55:46

sullivanva: Yes it's good. snd_pcm_oss should be loaded. Try to comment out the entries in /etc/modprobe.conf

I didn't know what to do about the intel sound driver. It seemed to be a problem, so I did this:

# find /lib/modules/ -name *intel* -exec rm {} ;

You saw my /etc/modprobe.conf above. I commented out snd-pcm and snd-seq. After a reboot the sound won't come up unless I run alsaconf. alsaconf puts the emu10k1 drivers in there and runs alsa.

I will try to comment out the emu10k1 lines, and reboot.

Edit:

It worked! Thank you. Sometimes less is more.
