You must use Windows 10, release 1803 or later for the USB audio to work properly since you could not change the USB input from 1-channel to 2-channels. Also, it has to be done on the full Sounds panel (open Control Panel on the PC and choose Sound), not the Windows 10 audio panel which you get when you open the sound device. The Sounds panel allows change without reverting to prior configuration, while the Windows 10 audio panel options always reverts to its default values.
