Click on both Show disabled devices and Show disconnected devices. If you don’t see your headphone from the list, right-click anywhere in the Playback window. Optionally, you can right-click your headphone and select Set as default device. If you see multiple audio devices are being enabled at the same time, disable other external speakers until only your headphone is left enabled. Right-click on your headphone audio device and then click on Enable. To enable your headphones in Windows 10, right-click on the Sound icon from the taskbar, then select Sounds. So, if you have not previously chosen your primary audio device yet, Windows will automatically choose the default audio device. If you have a built-in speaker or have an external speaker concurrently connected to your computer, you will have to tell Windows 10 which one to use.
Make sure the headphone is selected and enabled
