If you are not using devfs, you need to create the devices. There is a script in the ALSA-driver package to do that. Otherwise I can't help you because I never tried devfs and linux 2.5.x.

No. /dev/snd is a symbolic link to /proc/asound/dev, and that symbolic link was created by the script you mention. (I am not using devfs.)

So the missing "/dev/snd/controlC0" should actually be created by the ALSA modules in the proc filesystem as "/proc/asound/dev/controlC0". But only the timer device is there.

Warning: I'm no expert on any of this -- but -- I'm listening to sound right now using 2.5.69 (with devfs) and this is what I see:

There are NO symlinks from /dev to /proc. None.

/dev/snd and /dev/sound are real directories -- neither is a symlink.

Seems to me that any symlinks to /proc don't really belong in /dev. Any opinions to the contrary? (Remember: my sound is working just fine.)

I'm not using devfs, and I've had no luck getting ALSA to work on my i810-audio system. OSS works fine.

Is there a step-by-step writeup available for morons like me that haven't gotten ALSA working?

Thanks,
Andy

I have ALSA working under 2.4.21-rc1 using Erik's kernel patch, but I cannot get it to work under 2.5.69. I don't know what's wrong. I get Audio from my CD-ROM since it is connected to my sound card, but I get no sound from the Arts sound server in KDE. I get no errors and no warnings. I don't understand how it can't work. I'm thinking that the OSS emulation is broken. The ALSA version I have for 2.4 is 0.9.2. 0.9.3a is in 2.5.69, right? Have any bugs been reported to the ALSA people?

Regards,
David

Hi Andy !

The Problem seems to be that ALSA has moved their devices some weeks ago. In the alsa-driver-0.9.3a-Package (ftp://ftp.alsa-project.org) is a script called snddevices (attached) which creates the needed devices and links.

Execute it as root and all should be fine ...

Maybe this Script should be distributed with the Kernel too ?

Norbert

I use devfs, all is magic. All is [nearly always] correct.

[RFC] devfs [was Re: ALSA busted in 2.5.69]

Quoted 3 lines · David Ford

Are there any compatibility issues in 2.4 while using devfs under 2.5? I'm looking into it, but I'd like to hear that there are no problems before I jump into using it. I would love to hear comments from anyone using devfs. Good or bad.

Thanks,
David

Re: [RFC] devfs [was Re: ALSA busted in 2.5.69]

I've used devfs for years. A few people here and there gripe about it, my only gripe about it are drivers that don't [haven't yet] been updated to use it. In 2.5 those are rare. As to 2.4 vs 2.5, there aren't too many user visible changes and I think most of the new things for devfs (user visible) in 2.5 are also in 2.4.

My vote: devfs is _great_

Will I have any problems if I run this script even though I'm using ALSA 0.9.2 with 2.4.21-rc2 and whatever version is in 2.5.69-bk4?
