Yes, microphone gets detected instantly and it automatically changes to it in pavucontrol.
Then it likely requires some additional initialization outside HD-audio.
Or, if it's a headset jack (not a separate mic jack), there is still a chance about the missing headset initialization.
There are lots of other models for ALC662/ALC668, and on 4.19-rc, you can choose most of models via model option. Try each model.

It's hard to know, as it's pretty much vendor-specific. You can dig down the Windows, but I have no idea about Windows implementation, so can't give any hints, unfortunately.

at all when I talked or even muted the microphone physically.
I couldn't find "Mic Playback Switch" anywhere in either alsamixer or hdaanalyzer.
It's a mixer mute switch.
The microphone works perfectly fine under Windows, so I don't think it is the mic pin.
But the fact above indicates the possibility of the wrong pin, too.
Does the jack detection of the ext mic pin work?

setting alsa-mode[1-8] does nothing to help the issue.
There are several of similar bug reports around the web experiencing similar issues, and on different distros.
Microphone works perfectly in windows
I have a ASUS ROG G751JT, but this problem seems to happen with all
laptops
under the G751 name.
When you enable the loopback volume and switch, and unmute/adjust "Mic Playback Volume", and "Mic Playback Switch", do you hear the input from the ext mic? It's a route directly from NID 0x18 to the mixer NID 0x0b, then output mixer NID 0x0c, then outputs. So this can be used to verify the hardware routing.
If you don't hear via this route, it means that the input from the ext mic pin itself is broken, and it implies that something outside HD-audio codec.
