 |
|
Hey
I have this weird problem. When i boot, then a /dev/sound file is created instead of a directory. This means that /dev/dsp and other files are missing.
After boot the following modules are loaded:
| Code: | Module Size Used by

And my /etc/modules.d/alsa looks like this:
| Code: | # Alsa 0.9.X kernel modules' configuration file.
# $Header: /var/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.conf-rc,v 1.4 2004/11/16 01:31:22 eradicator Exp $
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
alias snd-card-0 snd-emu10k1
## alias snd-card-1 snd-ens1371
## OSS/Free portion
alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=1 |
I found a solution, but it has to be done after each boot, which is very annoying:
| Code: | rm /dev/sound
rmmod snd-mixer-oss
rmmod snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-pcm-oss |
And after submitting this solution, then i have:
| Code: | ls -l /dev/sound/
total 0
crw-rw---- 1 root audio 14, 12 Mar 25 22:31 adsp
crw-rw---- 1 root audio 14, 4 Mar 25 22:31 audio
crw-rw---- 1 root audio 14, 3 Mar 25 22:31 dsp
crw-rw---- 1 root audio 14, 0 Mar 25 22:21 mixer |
Any suggestion to a solution is greatly appreciated!

| if you are using udev, you may want to set 'RC_DEVICE_TARBALL="no" and RC_DEVFSD_STARTUP="no"' in your /etc/conf.d/rc. /dev/sound might be coming form those tarballs |

i have:
| Code: | # UDEV OPTION:
# Set to "yes" if you want to save /dev to a tarball on shutdown
# and restore it on startup. This is useful if you have a lot of
# custom device nodes that udev does not handle/know about.
RC_DEVICE_TARBALL="yes" |
because it should save the working configuration at shutdown. i cant imagine it has a relation to the problem?
I dont have a RC_DEVFSD_STARTUP option because im using sys-apps/baselayout-1.11.10-r4. |

it seems that your problem is precisely that you save a wrong configation at shutdown and you've got that at startup...
Besides the main purpose of udev is to create a fresh /dev every time you start and not recover a saved one (or then it's better use devfs, wich works with a static /dev and is much more tested ans stable).
I had a lot of problems of the same kind, with /dev/sound... they only disapear with:
(1) RC_DEVICE_TARBALL="no"
(2) use a udev from x86 (i avoid udev ~x86 since then!)
(3) all sound related modules compiled inside kernel, except the specific sound driver (snd_intel8x0 in my case) that goes as a loadable module
(4) remove snd_intel8x0 from /etc/modules.autoload.d/kernel-2.6 (it loads automagically)

u ment:
| Code: | | (1) RC_DEVICE_TARBALL="yes" |
right? |

no,
| Code: |
RC_DEVICE_TARBALL="no"
|
udev must create devices when system start up. If you say yes it will load a saved tarball (if exist, of course) and in your case it maybe loading an incorrect /dev/sound file...
(or maybe its something else, if you make a search for /dev/sound or /dev/dsp you will find hundreds of threads with that kind of problem...  )
another think i done too was emerge hotplug and added to boot level. hotplug is facultativ with devfs, but obligatory with udev.
good luck!
Edit, if udev is the problem, here a link full of information:

Just a small note here:
I was experiencing the same "udev-dsp-alsa" bliss for two weeks, switching between several kernels and ending up remerging anything alsa seven times in a row.
I just solved it, and it is too stupid to believe: you have to set the oss USE flag for the sound/* devices to be created!
If you use alsa-driver you must emerge it with uSE="oss" or you can wait till Larry the cow comes home...
No idea whether this also works with the in-kernel alsa.

|

I have been seeing the same problem of /dev/sound being created as a device file
instead of a directory. I have RC_DEVICE_TARBALL="no" and although I don't
have USE=oss in make.conf, it is enabled in the profile so those are not issues
for me. The work around I have been doing is:
| Code: | | /etc/init.d/alsasound restart |
but that has side effects in my session requiring me to log out and back in.
After some testing, I did find the problem and a workaround. I have been using in /etc/conf.d/rc:
| Code: | | RC_PARALLEL_STARTUP="yes" |
and found that changing that to | Code: | | RC_PARALLEL_STARTUP="no" |
causes /dev/sound to be properly created as a directory.
The differences I see in the startup is that with parallel startup, the consolefont,
keymaps and net.lo init scripts are executed during the alsasound startup.
Looks like there may be some concurrency issues with udev. |

I also have RC_DEVICE_TARBALL="no" and RC_PARALLEL_STARTUP="no"
If i have the alsasound init script added to start at boot level or default level it still create the annoying /dev/sound file instead of a /dev/sound directory.
I can fix this 2 ways:
| Code: | | /etc/init.d/alsasound restart |
or
| Code: | rmmod snd-pcm-oss
rmmod snd-mixer-oss
rm /dev/sound
modprobe snd-pcm-oss
modprobe snd-mixer-oss |
So my problem is still unresolved  |
