The mobo looks like having dual codecs like a similar one from
Gigabyte.  Try to apply the patch below on top of 4.12-rc kernel.

Note that you'll have no Master volume with this configuration, and
there are multiple PCM devices for different outputs (hw:0,0 and
hw:0,4 or such).  It should be switched via UCM profile by
PulseAudio.
