ALC892 & audio via headset problems after suspend

I have an Intel CM238 HD Audio Controller and the Realtek ALC892 card beneath I guess.

So the problem basically is in the title: after the resuming from suspension the headset (jack plug) doesn't play anything. Interesting thing that the sink is displayed in the pavucontrol. Moreover it fills volume bar when I play something.
There only way (that I found so far) how to make the headset working is a reboot.

Here some useful info:

I'm using Plasma/KDE and it is started from the xinit script as a user processes, so does the pulseaudio server, if it matters. Kernel is default: 4.14.8-1

What works:

• Mic

• Laptop speakers before/after suspend

• Headset before suspension

What have I tried:

• Increase volume wherever it's possible

• Change backend to phonon-vlc

• Tried to test via speaker-test w/o DE/WM

• Update everything

• Specify some models in /etc/modprobe.d/sound.conf for snd-hda-intel

• Use pasuspender /bin/true

• pulseaudio -k && kstart pulseaudio

• kill xorg
