[alsa-devel] No sound/mixer with new laptops on board sound - hda_intel ALC883
Hello list, I have a newer Medion Akoya MD 96420 Laptop (Mitac 8227D Barebone). The card is an Intel HDA compatible device, the codec is ALC883. There is no suitable model for the alc883 codec, tested all - no sound. So I think there is some work needed, I have not much knowledge in this area but would like to help if possible. Alsa-info.sh output with newest(hg 6120) alsa driver: http://pastebin.ca/997178

Here is a more informative alsa-info.sh output generated with the same alsa version but with model=medion (but still no sound): http://pastebin.ca/998349

I'm not an expert and don't even have an intel card. But I notice there is no output for amixer. Do you have alsa-utils installed? And when I look at the output of alsactl, all of the volumes are 0, muted. Have you tried turning up the volumes? After you install alsa-utils you should be able to run alsamixer in a console or terminal. Or even from a menu. In Gnome it is Applications->Sound & Video->ALSA mixer. I'm sure the equivalent exists in KDE. Maybe it is there already before alsa-utils. Sound is muted on initial startup, so will be silent until you turn it up.
It looks like your card is being recognized. Again, in a console (Ctrl-Alt-F[1-6], Alt-F7 gets you back to X) or terminal type aplay -L to see if any formats were configured. Here is what it looks like on my system:

Hope that helps.
I have alsa-utils installed, but alsamixer does not run, instead it gives this: ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more alsamixer: function snd_mixer_load failed: Invalid argument
So i cant modify the volumes...

Two things.
This looks like a bug in alsa lib. You can get the latest alsa lib hg snapshot at ftp://ftp.suse.com/pub/projects/alsa/snapshot/, compile it, and install it. The bug might be gone as things move very fast in alsa. If it isn't, it would be good to post this problem on alsa-devel.
You can edit /etc/asound.state directly. This file resides in /etc or /etc/alsa/ depending on your distro. Here is a representative entry from mine.
control.18 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 127' iface MIXER name 'PCM Playback Volume' value.0 103 value.1 103 }
What you want is to look for the same name (if you are using PCM), and then set the value.0 and value.1 to be something greater than 0. Try half at first (of the range) so you won't blow anything out if it is very sensitive. This at least gets you sound, though it isn't as convenient as using the mixer. You will have to be root to edit this and if you aren't familiar with unix editors (vim or emacs) you should probably use something like pico. Or Knotes or Text Editor in the gui.

With the newest hg alsa-lib it still does not work, same output.

The problem here is, that alsactl cant save the values, too with the same error than alsamixer: alsactl: set_control:1269: failed to obtain info for control #3 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #4 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #15 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #16 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #18 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #27 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #35 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #36 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #37 (No such file or directory) alsactl: set_control:1269: failed to obtain info for control #38 (No such file or directory)

This sounds like it could be a mismatch between the versions of the program alsactl and alsa-lib. It seems to be looking in the wrong place for information. The files that alsa looks in are by default installed in /usr/share/alsa. Some distros put them in /etc/alsa or /etc. Check if that is the case by looking at the timestamp on the files. If the newer files from the upgrade to alsa-lib are in /usr/share/alsa, you can put symbolic links to those files, or copy them to the location where your distro expects them to be.
After you updated alsa-lib, did you run /sbin/ldconfig? This updates the version of library being referenced for sharing. Could be the problem.
This doesn't seem to be the same problem as the first problem. What happens when you use aplay (aplay -v -D plughw:0,0 some.wav)? Can you run amixer (note, not alsamixer) in a console or terminal and get output? Is the output your changed file? Can you use the gui sound administration tools to play the test sound and does it work?
