Latitude 3590 external microphone

Hi,

I have problem with heatset and special with external microphone. I use standard headset from Samsung whitch is added to mobile phones. With mobilephone works fine, but with notebook is not working microphone and notebook still use his own internal, headphones are working without problem even on notebook. I have Windows 10 and latest Realtek driver. Only input device I can choose is Microphone (Realtek Audio) - internal microphone and Stereo Mix (Realtek Audio) - not working. When I connect headset nothing is changing, no new device addded in Windows, just sound is going from headphones instead notebook speaker.

Thanks for help

Tom
