Hi,

My configuration is http://www.alsa-project.org/db/?f=b6265238ab8c614754b1e7fc0af7e763cccf8f3b

I get the error:

$ 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 assume that my embedded soundcard is too new and not supported yet?

This doesn't seem to be related to pulseaudio. You can try to report this to the alsa developers: http://alsa-project.org/main/index.php/Bug_Tracking

(I have no idea what causes the error.)

Dont know what causes it.

I have reported to the alsa devs

You need kernel 4.12 for the audio from dual ACL 1220 codecs to work properly,
