I have to use the Audio Manager in an annoying way.
I can now no longer switch devices in the Playback devices, both front and back connectors are the same 'device'. When switching to Windows 10, the updater/setup automatically installed a 'Realktek HD Audio Manager' (which is the manufacturer), however that driver removed the ability to do that. I used to use the 'Playback Devices' menu to switch the default playback device depending on what I needed. In Windows 7 I used to have my Sound set up that I had my Headset plugged in at my front audio ports, and my speakers plugged in in the rear.
