Sound mute because of alsactrl error is known issue. I have no this problem now, after selecting my soundcard in menuconfig and recompiling kernel with built-in modules.
Maybe this will work too: http://pkgs.slitaz.org/search.sh?desc=linux-without-modules
no troubles for usb-soundcard, just MOBOin.
Before recompiling used setmixer command in autorun script.Posted 9 years ago # -
Thanks az_ua for your answer but I am a beginner with Linux and not very familiar with the different commands, could you give some more details on the procedure you suggest, if not too long.
Thanks in advancePosted 9 years ago # -
For slitaz4.0
Open any terminal, xterm or sakura. Try to run:alsamixer
if it works, there are no problems with sound driver.
Use <- -> M keys to set volume for master and pcm.
or 2 commands for Applications-Run:
amixer set PCM 20 on
amixer set Master 20 on
Or better this terminal command:
amixer set PCM 20 on && amixer set Master 20 on
Put it to home/YOUR_USERNAME/.config/openbox/autostart.sh
Launch from TERMINAL(NOT for App-Run menu, this gives error)
editor ~/.config/openbox/autostart.sh
Last line must be:#$(sleep 3 && wbar) &
Add this line:
amixer set PCM 20 on & amixer set Master 20 on &

As suggested I have checked Alsamixer and it works, but with Master and PCM set on 20 the sound is inaudible and the level has to be pushed at maximum 100% to start perceiving a very weak sound. (with the volume control of the tool bar at maximum)
Her are the last two lines of autostart.sh :# Wbar2 icon bar
#$(sleep 3 && wbar) &
Any idea of what to do? thanks for your suggestions .Posted 9 years ago # -
Are you ever tried this 1-word short command?
setmixer
If it works, just add setmixer as new last line to autorun.sh
if not read nextperceiving a very weak sound
This means PCM still at 'mute' state and no driver problem. Toolbar volume control is just copy of 'master' in alsamixer. For me amixer's 31 = 100% in alsamixer. Was not clear previously, about autostart.sh: Add NEW last line:
amixer set PCM 20 on & amixer set Master 30 on &
when you hear 'very weak sound' try to launch command:amixer set PCM on
Some hardware requires amixer set Front on. Anyway, i see you are not able to understand that MM in alsamixer = no sound. Press M button.Posted 9 years ago # -
Two points :
1)adjusting the levels (In the alsamixer panel) for Master, PCM... show that the highest volume is obtained at maximum gain : 0dB for PCM and Master and +1dB for Speaker (corresponding to a reference level of 100) and this looks logical (volume proportionnal to gain )
2) making the tests with new audio files gives good results !! obviously the two files loaded for the initial tests were of bad quality.
Thanks a lot for your suggestions which helped me to understand better the basics of Alsamixer.Posted 9 years ago # -

(Try with this command above...)
root@slitaz:~$ alsactl init
Found hardware: "ALI5451" "Analog Devices AD1981B" "AC97a:41445374" "0x104d" "0x8158"
Hardware is initialized using a generic methodCa marche avec ma configuration (it work's with my configuration),
