Enabling loopback in alsamixer: http://i.imgur.com/lNo6e7T.png
And unmuting more and more things in "Mic Playback Volume" in hdaanalyzer: http://i.imgur.com/H0HiOhy.png made white noise come from the headset. However it did not change or react 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.
