[alsa-devel] Bug with alsamixer: ALSA lib simple_none.c:1550:(simple_add1) helem (MIXER, 'Master Playback Switch', 0, 1, 0) appears twice or more

[Rudolf Schmidt]

Hi guys,


I want to report a bug or some kind of problem with alsa


  $ alsamixer
ALSA lib simple_none.c:1550:(simple_add1) helem (MIXER,'Master Playback 
Switch',0,1,0) appears twice or more
cannot load mixer controls: Invalid argument


I tried to figure out what is going on, tried a lot of things, removing 
packages, installing packages, removing pulseaudio etc.


Nothing helped. I found a gentoo user who reported to had the same 
issue, upgrading to kernel 4.12 helped, in particular that patch: 
https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?h=topic/hda-dual-codecs&id=7beb3a6e9335d13872f24566b451f8371edd238f


So I also upgraded to kernel 4.12 but in my case I have still the same 
problem.


Here is my config:

Hope you can help me.
