The above steps relating to Windows 8 don't work for me in Windows 10. When I set the default to Line Out 1/2 and try to play sounds through Windows Media Player or YouTube the players won't even play as if there is an audio driver issue. Sound plays through the Audiobox just fine when using my DAW software. Computer is set up with the universal control software. I'd like to have sounds playing in Windows Media Player to play through the Audiobox and associated speakers instead of my computer speakers.
