Hi Jesse,
Software driver can be enabled/ disabled by opening/closing of the jumper J15 pins 1 and 2.
When you open the jumper pins, software will be enabled and pass through worked.
For running scripts, the software should be disabled, close the jumper J15 pins 1 and 2 and run the scripts available in below path to make it work.

I think you have already closed the jumper pins and tried the script (ADV7625ES2C-VER.1.2c.txt.zip) in above path right?
Could you please confirm which script you tried?
For the tried scripts, whether you found no output or what?
What is the source and sink that you have used?
Best Regards,
