Topic: Accessing RME Babyface Pro FS's Optical Input in Class Compliant Mode

Hi fellow Linux users and RME, was wondering if anyone knows how to access the optical input on Linux when in CC. I've been going at it for some time and had no luck when trying to search up the option online. I can see that it does detect the input when viewing the volume meter on the Babyface but that's all I got.
