MediaPlayer does not display an mp4 if there no speakers connected to the PC's

ADDITIONAL SYSTEM INFORMATION :
Running Java 14.0.2, JavaFX 16ea+1, NetBeans using Maven, Windows 10.

A DESCRIPTION OF THE PROBLEM :
I have used a sample for years that plays a video. For the first time this year I am using a PC that has sound going thru a USB connection. That is fine and the video plays. But if I remove the USB my Win PC tells me there are no speakers which is correct. Now, when I run the program, its only a stage, scene and media player with a hardcoded mp4 file location, the window opens and nothing but a white background appears. No log messages, no exceptions.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Remove all speakers on any program that plays an mp4 with the Media Player. Beware, laptops with built in speakers will never exhibit this problem. Desktop boxes that default to an internal speaker will also never exhibit this problem.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Play a video
ACTUAL -
Does not play video
