Roon uses a custom drawing engine for performance and cross platform reasons… our entire user interface is written in OpenGL, which gets us the performance and portability we desire long term. Unfortunately, this means the graphical parts of the application are built like a video game, and less like a normal application.
I fear that JAWS and others are built by hooking into the built-in Windows text areas, and then they won’t work with Roon.
If you have a screen reader that works via real-time OCR techniques, it may work better
