   As it says: The sound on my laptop remains in a disabed state. The LED indicating sound=off is constantly lit, pressing the on-off button has no effect. Sound not working is not a problem for me, I had it off most of the time anyway but the problem may be related to my issue with wlan not initializing properly. It seems to me there is some kind of driver-conflict.

   Don't know exactly where to start with providing information. Perhaps the output from lsmod is a good start. Here it is:

   @Mojo: Yes, I am still using the wl-driver because I haven't yet found out how to get it working with the b43 driver. ;-) Perhaps there is a relation with this problem meaning there is some kind of a driver conflict. The output I posted yesterday seems to point in this direction.
   The laptop is an nc6320. I upgraded the OS to slitaz earlier this week.

   I doubt the wifi driver is related to the audio problem.
   Meanwhile see if blacklisting b43 works:
   # echo "blacklist b43" >> /etc/modprobe.d/blacklist
   Post the output:
   grep Codec /proc/asound/card*/codec*
   ls -la /proc/asound
   aplay -L
   aplay -l
   lsmod | grep -i snd
   amixer
   Attach a screenshot jpeg of alsamixer maximized.

   The screenshot will not be forthcoming as it seems the application doesn't even start. When clicking on it (Applicatons > Multimedia > Alsamixer) my screen flashes briefly but nothing pops up.

   As to the wireless problem, I will post in the other thread.
   thnx!

   Found on the forum that you can start alsamixer from the command line.
   That worked. Image attached.

   When checking the other audio problem, I re-issued the commands I posted before but now the output looks different (like better).

   This looks very similar to what I saw in the output from Verault and very different from what I got the first time. (at that moment my wireless was still not working)
   When pasting the sequence in the command prompt, one of the commands (!) triggered my audio and it came to life. I was already able to play some mp3 files with alsaplayer.

   Looks like everything is falling in its place eventually. This is how my desktop looks

   Just did another reboot to verify the erratic behavior I noticed. The script lines used to generate the requested output (by mojo) fix my sound card albeit temporarily.
   It is the first line which does the trick:
   # grep Codec /proc/asound/card*/codec*

   When executing this command, the audio-disabled-led immedialtely switches off and my audio seems ok. After a while, it disables itself again without me doing anything.
   However, re-entering the above line immediately puts the audio back on.
   I have done it at least five times by now and it didn't fail a single time.

   What could possibly be going on here?
