• My motherboard: ASUS X99-DELUXE II (https://www.asus.com/ca-en/Motherboards/X99-DELUXE-II/)

Solution

A line in is something different, not meant for microphones. It's completely normal. It is used to say connect a MP3 player into the computer for whatever purpose you may need it for. Some motherboards don't even have them, but your motherboard appears to, and can be seen as the blue input in the back. More info is avaliable on Microsoft's site on this link: http://windows.microsoft.com/en-us/windows/connect-audio-device#1TC=windows-7 I hope I helped, have a great day!

I knew it actually, I just didn't make the link between the ideas. Thanks for your help. I've plugged an rca to 1/8 cable from my sound mixer and it states ready instead of Not plugged.
