[alsa-devel] No sound/mixer with new laptops on board sound - hda_intel ALC883

[Kristoffer Janke]

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...
