1. From the start menu search for "Sound" and open the Sound control panel.
2. Select the Recording tab then right click in the window and click "Show Disabled Devices"
3. A new item called "Stereo Mix" should appear in the list. Right click this and click Enable.
4. From vMix, go to the Audio Mixer and turn down the headphones volume to 0.
