alsamixer = big problem


I upgraded my kernel to 2.6.11.2 on my slackware 10.1 .

But my sound don't work.
I have a ac97 , and i run the alsaconf .

It sees my ac97 .. and install it ..

But every time i try to run alsamixer i get this error:

$ alsamixer

alsamixer: function snd_ctl_open failed for default: No such file or directory


Any suggestions?

What is your "lsmod" output? Looks like you have no modules loaded. And also, I don't think AC'97 is the actual soundchip. Do you have the previous kernel, or was it the default Slack kernel? If so, you could also post the output of "/sbin/lspci" to show the audio controller.

And yes, i have the previous kernel(2.4.26) working. Including the sound.

What could i be doing wrong?

Welcome to LQ!
sorry I forgot before...

Looks like you don't have the proper modules loaded for that via soundchip.
I don't even see snd-via82xx in your output.

One of our comps has that chipset, and this is his "lsmod"
Code:
mingdao@peter:~$ lsmod
Module                  Size  Used by    Tainted: P  
snd-pcm-oss            37956   0 (autoclean)
snd-mixer-oss          13296   0 (autoclean) [snd-pcm-oss]
nvidia               1628032  11 (autoclean)
snd-via82xx            13504   0 
snd-pcm                60928   0 [snd-pcm-oss snd-via82xx]
snd-timer              14916   0 [snd-pcm]
snd-ac97-codec         47468   0 [snd-via82xx]
snd-page-alloc          6484   0 [snd-via82xx snd-pcm]
snd-mpu401-uart         3440   0 [snd-via82xx]
snd-rawmidi            14144   0 [snd-mpu401-uart]
snd-seq-device          4336   0 [snd-rawmidi]
snd                    32644   0 [snd-pcm-oss snd-mixer-oss snd-via82xx snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device]
soundcore               3844   4 [snd]
All the VIA chipsets use the same instructions for ALSA. If you have
the soundcore module in your kernel SOUND_CONFIG=m then all
you need to do probably is modprobe the modules from that page
on the ALSA website. Give it a try, and post back.

Still the same error.

You're still missing the soundcore module
Code:
soundcore               3844   4 [snd]
Have you read those ALSA instructions?
Quote:
Most modern distros come with soundcore compiled as a module. You can check this in numerous ways. The easiest way is to type.

modinfo soundcore

If this command returns that you have this module, then you don't need to recompile your kernel.
In Slack you'll have to issue
Code:
mingdao@james:~$ /sbin/modinfo soundcore
filename:       /lib/modules/2.6.7/kernel/sound/soundcore.ko
description:    Core sound module
author:         Alan Cox
license:        GPL
alias:          char-major-14-*
vermagic:       2.6.7 preempt K7 4KSTACKS gcc-3.3
depends:        
mingdao@james:~$

# modinfo soundcore
modinfo: could not find module soundcore

So it means that i have to recompile the kernel right?
But the kernel is already recompiled to 2.6.11.2 ... maybe i did something wrong..

In the SOUND i have this:

<*> Sound card support

In the ADVANCED LINUX SOUND ARCHITETURE:
<*> Advanced Linux Sound Architecture
<*> Sequencer support
< > Sequencer dummy client
<*> OSS Mixer API
<*> OSS PCM (digital audio) API [*] OSS Sequencer API
[ ] Verbose printk
[ ] Debug

And my ac97 in PCI DEVICES:

<M> VIA 82C686A/B, 8233/8235 AC97 Controller

Do i need to change anything? Is this enought? What should i do?

That is what the ALSA instructions say. Someone else may have
some hack, but I always just follow the instructions.

I believe you can issue "make xconfig" and just change the line
Sound card support from a check mark to a dot -- the check means
Y for built in, and the dot means M for module. And if you only change
something else to modules, this is what I believe -- but check this
and make sure it's true. I have never tried it, but with the 2.6.x
kernels if you just change something to modules, I think you can issue
$ make modules
# make modules_install
and then reboot and you will be okay.

Here is the sound portion of my 2.6.7 kernel's .config if it would
help you to look and compare to yours. You will need the VIA82XX
instead of the EMU10K1 I have for my Audigy.
Code:
#

Hope this helps --
