 Posted: Sat Mar 19, 2005 7:12 pm Post subject: Moving from devfs to udev sound problem! [SOLVED] |
 |
|
Kernel: 2.6.11-r3 (gentoo-dev-sources)
Compiled without devfs, udev 0.45
Used to have sound working dandy in devfs, now its not working with UDEV.
First of all, its weird I dont have /proc/asound
lsmod output after running /etc/init.d/alsasound restart
| Code: | bash-2.05b# lsmod
Module Size Used by
snd_page_alloc 8520 0
soundcore 8672 0
nvnet 69160 0
nvidia 4558652 12
agpgart 29028 1 nvidia
|
Output of actual command.

I dont know what to do. I have tried some other stuff with no luck.

Your alsa modules are not loaded, soundcore module is the OSS one, /proc/asound appears only after they
are loaded.
Your output shows that loading alsa module failed. Where they compiled together with the kernel, or separately ? |

Well, I compiled the kernel with support for those modules. I specified intel 8x0 since its compatible with the chipset. I even did a make distclean before recompiling without devfs support to make sure that everything was recompiled. I also deleted the /lib/modules/<kernel> directory before remaking and reinstalling all modules. Any idea how ot know if udev is dong the proper loading?
I have a feeling that it has to do with udev solely, but dont know of proper troubleshooting techniques. I cant find the proper path or name for *anything* related to a sound device in udevinfo. I do have both oss and alsa compiled as kernel modules... I only use the alsa ones. I left it in case I needed OSS for backward compatibility or something.
I compiled them built-in the kernel and they seem to be working. So I would be inclined to say that its something else.

I will retry building them outside then. I do prefer to have them as modules

Solution:
After building everything in the kernel I started systematically turning modules/off and on and stumbled upon this:
| Code: |
Device Drivers-->
Sound-->
[b] <*> Sound card support[/b]
Advanced Linux Sound Architecture --->
Open Sound System --->
|
So once this *Sound Card Support* was built in the kernel, udev picked up from there. Alsaconf worked flawlessly as lsmod shows below.
| Code: | snd_ioctl32 26368 0
snd_pcm_oss 51488 0
snd_mixer_oss 17280 1 snd_pcm_oss
snd_seq_oss 32832 0
snd_seq_midi_event 7680 1 snd_seq_oss
snd_seq 53504 4 snd_seq_oss,snd_seq_midi_event
snd_seq_device 7760 2 snd_seq_oss,snd_seq
snd_intel8x0 30528 1
snd_ac97_codec 76128 1 snd_intel8x0
snd_pcm 84620 4 snd_ioctl32,snd_pcm_oss,snd_intel8x0,snd_ac97_codec
snd_timer 22152 2 snd_seq,snd_pcm
snd_page_alloc 8520 2 snd_intel8x0,snd_pcm
nvidia 4558652 12
agpgart 29028 1 nvidia
nvnet 69160 0
|
This of course makes sense since sound card support being in the kernel seems to have some magical effect
