To hear the sound CD playing with alsa driver and kernel 2.6.x, you have to increase the value of Line1 with Volume Control, or aumix. But after reboot, the setting is gone. That means I have to do manually. Anyone know how to save this setting?

The same problem apply with my normal sound. So it mute by default. So I have to add two lines in my startup script to solve this problem:

amixer sset Master 20 unmute >/dev/null
amixer sset PCM 20 unmute >/dev/null

But unfortunatelly add these two lines:

amixer sset Line 20 unmute >/dev/null
amixer sset CD 20 unmute >/dev/null

doesn't work.

$ amixer sset Line1 20 unmute >/dev/null
amixer: Unable to find simple control 'Line1',0

So, anyone know how to solve this problem?

Do you have alsasound script in /etc/rc.d/init.d ? You must have it in the directory and also in the directory corresponding to your runlevel.

No one told me about that. I don't have one. So could you tell me how to make one?

As far as I can remember (I'm not at linux computer right now), download alsa-driver.xxx.tar.gz from www.alsa-project.org and then compile. Then check inside utils/. There will be alsasound script inside there. Or you could try this one:
http://www.alsa-project.org/alsa/dri...s/alsasound.in

Just rename it to alsasound then put inside the /etc/rc.d/init.d/ then softlink it to your runlevel.

I downloaded the script and run it in console.
# alsasound restart
Shutting down sound driver: !!!alsactl not found!!! done
Starting sound driver: snd-emu10k1 done
ERROR: alsactl not found

But that does not increase the value of Line1 ( the others are Vol, Bass, Trebl, Synth, Pcm, Apkr, Mic, CD, Video ).

Any idea????

How did you install the alsa? Did you follow the instaruction on the alsa-project website? Because alsactl should be present if you installed them correctly. Did you install alsa-driver, alsa-utils and alsa-lib correctly?

# which alsactl
/usr/sbin/alsactl

#echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin:/root/bin:/usr/sbin/

# alsactl
alsactl: Specify command...

I installed by sources.

It is the correct location. Try looking into your source file for alsasound. Maybe it was compiled to fit your system. I mean in the alsa-driver. But for me, when I installed from source, it will copy the 'alsasound' file to the correct runlevel. I think this part of script is correct:

function stop() {
#
# store driver settings
#
if [ -x $alsactl ]; then
$alsactl -f $asoundcfg store
else
echo -n -e "${rc_warning}!!!alsactl not found!!!${rc_reset} "
fi

Did you run the script in root account? Exactly what I did were:

1. Put the script in /etc/rc.d/init.d/.
2. Add softlink in /etc/rc.d/rc3.d/ and /etc/rc.d/rc5.d/ to alsaound script.
3. Run alsaconf.
4. Reboot.
5. I see that the alsasound is loaded.
6. Then I see that the mixer setting was set to default.

Yeah I forgot something. Is there alsactl script in the /etc/rc.d/init.d directory. Maybe the alsasound script was refering to the script, not the /usr/sbin/alsactl.

I did that with root account. I don't have rc3.d and rc5.d directory. I use Slackware. So I make them. Put the alsasound script into them. I copy alsactl script from /usr/sbin/alsactl to /etc/rc.d/init.d directory. Run alsaconf. Reboot. Got no luck. I still have to increase the value of Line1 with aumix, or kmix, or Gnome Volume Control if I want to hear the sound of CD music.

On my Slackware machine, I added these lines to my rc.local file:

rexima vol 90
rexima pcm 90

I find moving them much higher than 90% makes everything sound like crap, but that might just be my hardware, it might work differently on your system.

Damn, that's the solution So I add this line in my startup script (rc.local):

rexima line1 50

That's all. My vol and pcm is already increased by this command in startup script:
amixer sset Master 20 unmute >/dev/null
amixer sset PCM 20 unmute >/dev/null
