Ok, everytime I compile kernel 2.6, I alwayz get this trouble....
This is my config....
#
# Sound
#
CONFIG_SOUND=m

#
# Advanced Linux Sound Architecture
#
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_HWDEP=m

CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_SEQUENCER_OSS=y

# CONFIG_SND_ALI5451 is not set

CONFIG_SND_EMU10K1=m
# CONFIG_SND_KORG1212 is not set
# CONFIG_SND_MIXART is not set
# CONFIG_SND_NM256 is not set


I run alsaconf as root. Look fine.... Then I try to alsamixer. Here's what I got:
alsamixer: function snd_ctl_open failed for default: No such file or directory

What's wrong???? When I play music, it looks fine but no sound out.....
I m using Slackware 10 and kernel 2.6.7
Thank you.....

The (Almost) Sure Way to Solve Slackware Alsa Problems:

1. Remove the Slackware alsa packages you currently have installed.
2. Compile your kernel with support for soundcore (ie. sound) only, and without support for oss or alsa.
3. Compile and install alsa-driver, alsa-lib and alsa-utils from source according to the exact instructions for your soundcard at http://www.alsa-project.org/
4. Run alsaconf and alsamixer followed by alsactl store.
5. If necessary, get /etc/rc.d/rc.alsa from the Slackware source tree, put it in /etc/rc.d and make it executable to take care of loading the sound drivers and mixer settings at boot.

Try uninstalling all 4 alsa packages (alsa-driver, alsa-lib, alsa-utils, alsa-oss). After that compile alsa-lib and alsa-utils from source (Slack 10 CD4, or www.alsa-project.org). Since you compiled alsa into kernel you dont need alsa-driver and alsa-oss.

This is my 2.6.7 kernel config (I compiled in most of the stuff):

Hey,

I compile my kernel again. This time I don't include oss and alsa support. I just make soundcore as module. I remove alsa package then install from source.....

Run alsaconf...

Loading driver...
/usr/sbin/alsaconf: line 664: rcalsasound: command not found
Setting default volumes...
Saving the mixer setup used for this in /etc/asound.state.
/usr//sbin/alsactl: save_state:1061: No soundcards found...

And I don't have /dev/mixer, /dev/sequencer, /dev/midi.
what's wrong????

Hello,

I compiled kernel 2.6.6 kernel with alsa support fine and without compile alsa programs, just use the last alsa packages.
Here is my config for sound (card : SB 5.1 live) :
CONFIG_SND=y
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_HWDEP=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_SEQUENCER=m
CONFIG_SND_SEQ_DUMMY=m
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RTCTIMER=m
CONFIG_SND_MPU401_UART=m
CONFIG_SND_DUMMY=m
CONFIG_SND_MPU401=m
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_EMU10K1=m

all other sound features are not set

I check when I use kernel 2.4.26, I got /dev/mixer and /dev/midi. But when I use my own kernel, 2.6.7, there is no such device....

Maybe this is the cause of my problem????

There are 4 alsa packages: 1. alsa-driver, 2. alsa-oss, 3. alsa-lib, 4. alsa-utils
When you are compiling new kernel (2.6.X) you have to uninstall all of them and compile them from source for new kernel.

I do exactly the same as Kovacs said and it always works for me.

In the alsa-driver package is the script snddevices
this will provide /dev/mixer etc

from inside the alsa-driver dir run
./snddevices as root

then
chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi

(from the alsa quickinstall doc at the alsa site)

Ok, I am tired now..... I use kernel provided by Patrick. I use alsa-driver from him. Now I can enjoy music. Go to h*ll with my own compiled kernel. Maybe this is the message from The Life that I should not wasting my time tweaking Linux. I should work with Linux. Linux should save my time not waste my time.

Now I am looking for installing kernel 2.6 provided by Patrick......
Thanks guyz......

Ok, I got clue now. The problem is kernel 2.6.7 is not support my sound card. I try to modprobe with Patrick's kernel but still null. sound is hell with kernel 2.6.7.

Bye bye......

Creative sound cards are supported by the latest kernel, which I guess you mean as you enabled emuk10k1. They are supported by ALSA (and OSS for that matter).

What card do you have that is not supported?

That's not true, I always used officials alsa packages and always use kernels from www.kernel.org, alsa packages work fine.

[edit]
I must add that often sound problems come with the reboot after a fresh kernel compile but I used to fix that by rm /etc/asound.state (wich store alsa settings) and reconfig alsa (alsamixer, alsactl store)

How can you use alsa-driver,oss,lib packages compiled for 2.4.26 on a customized 2.6.x?????
It doesnt work!!!

Hi!

Does anybody who has Creative Sound Blaster Live! has configured it (with alsa) to work with 5.1 speakers?

I managed that it works (bad) as a stereo (2 speakers left, 2 right) with woofer but it's still FAR from good.

Anyone has asound.state to share or some advice?
