How do I connect an external microphone

HP Recommended
Pavilion x360
Microsoft Windows 10 (64-bit)

I am interested in connecting my microphone to my laptop via the combination headphone/mic 3.5mmjack. I initially connected my microphone (which ends in 3.5mm connector) directly into the port. This did not work as the microphone output is three poled and not four poled like the laptop's input. 


I then bought a 4 pole adapter that splits the headphone and mic channels. This worked once and then stopped working. I know the device works as the headphone channel works fine. Therefore I have two questions:


1. There are two 4 pole configurations: AHJ (also known as CTIA) and OMTP. The splitter I have is AHJ : is the laptop jack also AJH?


2. I believe the reason the mic does not work has to do with the default sound settings. Plugging in the device does not show any new devices. Are there are specific setting I need to set in order to utilize the external mic?


3. Do you have any recomended software or cheap adapters that could fix the problem? 


Thank you

The combo jack does not work with a stand alone microphone and 50/50 successful rate when using a splitter. Please try
