Dell Latitude 5400 switch to headset mic when plugged

Pulseaudio doesn't switch Built-in Audio Analog Stereo input port to "Headset microphone" when headset is plugged in.
I've read many topics regarding similar problem here and in other forums, but no solution worked for me.

The mic itself works fine and i can use it by switching from "Internal Microphone" to "Headset Microphone" in pavucontrol Input Devices manually (of course, with pactl as well). But i'd like it to be switched automatically after headset is plugged in.
Output Device is switched from "Speakers" to "Headphones", as desired.

I'm not sure whether this is ALSA or pulseaudio issue. When headset is not plugged, Port in pavucontrol Input Devices tab dropdown list is named "Headset Microphone (unplugged)", also there is "Microphone (unplugged)".
When headset is plugged, it is immediately renamed to "Headset Microphone" (and also "Microphone") right in dropdown list. So pulseaudio detects microphone presence, but doesn't switch to it.

Difference in `pactl list` output ('-': unplugged, '+': plugged):

I tried tons of fixups and their combinations for snd_intel_hda model parameter found in sound/pci/hda/patch_realtek.c, none worked. Unfortunatelly, it's quite hard to try all of them.

Re: Dell Latitude 5400 switch to headset mic when plugged

What are your relevant ALSA controls?

aplay -lL
amixer -c0

sometimes this is a driver level switch, assuming you are currently not loading a custom model parameter so we get the default view.

Re: Dell Latitude 5400 switch to headset mic when plugged

         * source will be created, otherwise the headset or microphone can't be used
         * to record sound since there is no source for these 2 ports. This issue
         * is observed on Dell machines which have multi-function audio jack but no
         * internal mic.

As i understand, there should be some configurable "availability groups" of ports. Maybe something to customize in /usr/share/pulseaudio/alsa-mixer/ ?
