Laptop internal mic doesn't work anymore

Hi!

So, the title pretty much says it all. I'll be a little more specific here.
I just tried talking to Cortana, because I wanna enter the 21st century too, and she ignored me as if she knew my ex.
Turns out she just couldn't hear me.
Double checked with Win10's native Voice Recorder and that didn't record anything either. Tried using a plug-in mic (actually the standard PS4 earplug/mic, if that makes any difference), but that didn't do anything either and I know that thing worked at least up until I just had to pull it out with a leatherman.

I've gone through all the suggestions google came up with: enabling the mic, un-muting the mic, updating drivers.
Only thing I didn't do is go through Device Manager and uninstalling device to re-install drivers as I am afraid I'm not gonna be able to find the mic at all anymore.

Weird thing is, I just got this laptop two days ago and during the initial start up I talked to Cortana. Then yesterday I spent an eternity waiting on a massive update and now the current problem has arisen.

System:
MSI GS63VR 7RF-219NL
Standard, outta the box. Didn't do anything other than fiddle with the fancy keyboard lights and realise I am not acting my age.

Windows 10 (obviously) Home 32-bit, 1709 build 16299.125
Nahimic 2+ Audio Driver
Dragon Centre 1.2.1706.1501

I am assuming my display drivers aren't very relevant here.

Any ideas? I'm guessing that massive update screwed things up, but that's all it is: guessing.

What you need to try is:
right click speaker (sound) icon on taskbar and choose recording devices.
1-Make sure the right device is set as default.
2-select the default device and choose properties. (make sure in "device usage" it is set to enabled)
3-click on levels tab and make sure levels are set correctly
4-in advance mode make sure both boxes are checked (exclusive mode)
5-In device manager make sure the driver is working correctly

if non of this get the mic to work then re-installing the driver is nothing to be afraid of!
Check driver in device manager and see if you have a rollback driver option (if you have one then it means that windows has updated the driver and you can go back to the earlier one.) if not get latest driver from manufacturer and install that one.

Since the mic isn't working I suppose I'm not any worse off if I can't find it after uninstalling. I'll have a look at that later when things are less... Motörhead here.
Thanks for the help.
