I am using an Alienware Alpha R2. It is connected to external monitor with a 3.5 jack but has no built in microphone. The Alpha doesnt have a 3.5 jack but i connected a Audioengine D3 to it so i could connect my Hyper X headset (with microphone) to the Alpha. I have checked the drivers for the D3 in device manager and it says that they are up to date. I have gone into the Sound menu by right clicking the "speaker" icon on the bottom right and selected recording devices, then right clicking in that menu and making sure that "show disabled devices" and "show disconnected devices" are both selected and i dont see anything there. I have also tried connecting my Hyper X headphones directly to the monitor and i get the same result. No recording devices show. I cant think of anything else to do. Any help would be appreciated.
