Comment 22 for bug 1596381

to David Ford (djfordz-q) thank for help, but it doesn't make external mic to work
I've setup option:
`options snd-hda-intel model=laptop-dmic,headset-mic`
and reboot notebook - doesn't help, internal working, external not.

Searching an internet, help to find a solution that works.
So then I've install "alsa-tools-gui" launch "HDAJackRetask", select codec ALC256,
checked "Show unconnected pins" then check pin ID: 0x19 and select "Microphone" then hit "Apply now".
Started pavucontrol for checks and it work.
Both of them built-in, and external headset microphone works now.
So launch "HDAJackRetask" and make a permanent change, hit "Install boot override"
After reboot it work for all users on notebook.

P.S. As for other models and codecs it may be other pins number in "HDAJackRetask" utility.
