Hi!

I am relatively new to this comile-my-own-kernel stuff ... but mostly works good for me.
I was always just trying some little things, like an openMosix-patch or so... and when I compiled always some little things were not pefect but it was ok, as long as it was a test and the tested thing was ok. ...

But now I have a big problem.

I compiled a 2.4.26 kernel, which is the same as the working one, with the /boot/config-ide-2.4.26 as config. Well, it started but I have no sound (erorr comes later) ... well ok... I had exactly this errormessage beofre...

So I rebooted my old kernel (which I did not touch nor change somethin in it's section in lilo.conf) and... DAMN! The same error message!!!

Like I said, this error wasn't new to me, but until now it did not effect the system when I booted my old working kernel...

Since I never had to deal with Linux's sound system I know NOTHING about it. It always worked after the install

So, now here's the Error-Dialog coming up when KDE's login is over:

------------- Informativ - aRts-Meldung ------------------------------------------------
Sound server information message:

Error while initializing the sound driver:

device: default can'T be opened for playback (No such device)

The sound server will continue, using the null output device.
------------------------------------------------------------------------------------------

Don't know what the heck I can do against that

Is it possible, that "make mrproper" killed something off?

As additional information: Slackware 10.0 on Fujitsu Siemens Amilo A

Any help is welcome!

Greetings, Sascha

since their both 2.4.26, mayb your modules have been overwritten in /lib/modules

so,..what can I do..

a) to check for this
b) if it's like that, do to get sound up again?

If it is a help, I remebers that sound chipset(?) was something like VIA?86??-blah

Thanks for your intrest!

Greetings, Sascha

go into your kernel configs and make sure your sound card module is built, or if it is, make sure the module is getting loaded

Hmm...
Ok, for I am not sure how to do all this... here is what I#ve done so far:

lsmod shows me a loaded module 'via-rhine' don't know if thats something usefull/needed but it's the only thing in that direction...

Then, in /etc/rc.d/rc.modules is an out-commentet line which would load the module 'via82cxxx_audio' (along others) and I think I remember to have seen somthing with via...

Now I tried to modprboe exactly that module but.... not found...

modprobe: can't locate module via82cxxx_audio

Ok... and I looked into /lib/modules/2.4.26/kernel/drivers/sound ... there are a lot of entries ( .o ) but nothing with via...

I tired to locate somthing with via on my system... but I can only find it in /usr/src/linux/drivers/sound/ ....

In my /usr/src/linux/.config I have turned on "Sound card support" ... and "VIA 82C686 Audio Codec" but not "VIA82c686 Midi" ...

Does that help you to help me? :-)

Thanks fopr your time!

Greetings, Sascha

Just had a look into /var/log/messages and found this one, directly after booting ...

modprobe: Can't loacte module snd-via82mm

A line before this ALAS is loaded without problems... I think this is a good sign, eh?

But what about the unloadable module?

Greetings

I don't know if this will help you, but via82cxxx_audio is the OSS driver, and via82xx is the ALSA driver. AFAIK, you should use via82xx, and check in /etc/modules.conf that it is spelled correctly.

Hmm... I am getting some similar feeling.

Have been looking a round a bit more on my system.

lspci tells me I have a "VT8233/A/8235/8237 AC97 Audio Controller" and there is no 'c' in that...

So, I looked into /etc/modules.conf and there some aliases... and one says "alias snd-card-0 snd-via82xx" ...

Greetings, Sascha

It seems to me, that this damn module simply isn't there ... god knows why...

I did a 'find / -name *via82* ' and a lot of via82cxx were found. the only via82xx.* that were found are from the kernel 2.6.8.1 sources ... but thats by far not the one I am dealing with ...

2.4.26 does only have a lot of via82cxxx.* file...

but I have no clue how I could solve this problem...

Maybe I have to patch it into the kernel????

So frustrating :-)

Sascha

At the top of your linux kernel tree (usually /usr/src/linux), there is the file .config; open this file and locate the comment stating that this module is not built, and change it so that it is built as a module.

Yves.

Bad news.... there is no entry for via82xx in the .config ... only for the via83cxxx ...

I tried to install also-driver and libs... but that seemd to be not enough...

Now alsaconf finds my soundcard again...and conifugres it,... but nothing more... still doesn't work

Sascha.

well open up alsamixer and make sure they arent muted
also, check your dmesg for any errors when loading the module

Well alsamixer won't come up... and the channels are Muted... I know ... but that isn't the point ... I am still getting this damn error on kde-login ( look into my first post) and the damn module just can't be loaded...

modprobe snd-via82xx tells me:

/lib/modules/2.4.26/kernel/sound/acore/snd.o: unresolved symbol unregister_sound_special
/lib/modules/2.4.26/kernel/sound/acore/snd.o: unresolved symbol register_sound_special
/lib/modules/2.4.26/kernel/sound/acore/snd.o: insmod /lib/modules/2.4.26/kernel/sound/acore/snd.o failed
/lib/modules/2.4.26/kernel/sound/acore/snd.o: insmod snd_via82xx failed

Hell, I don't know why the install routine from alsa doesn't put the module where it belongs or whatever the problem is ...

Thanks for all your time! I'll have to go for now... but I#ll be back tomorrow ... thanks for your help 10000000 times so far! :-)
