Just added a Foldback monitor, I am using  a Nivida GTX 1650 Super Graphics card.  I used a

DVI-D to VGA adapter to output to the Foldback monitor.  The Foldback was perfect, but I noticed

that I lost my audio from EW when playing Videos.  As soon as I removed the DVI-D to VGA adapter, the sound returned.  Is there a Windows 10 setting that need to change?

Check to what Windows has selected as the Audio Out with the DVD-I to VGA adapter is the same as what is selected without it. More than likely Windows is doing stupid Windows stuff to change that.
