A 2015 forum thread discussed S/PDIF Toslink output with the Teensy 3.1. One of the options discussed was simply adding a red LED, connected to pin on the Teensy, with a resistor to limit brightness, and point it at the end of the fiber optic connector. I would like to try this with a Teensy 4.0 and the current audio library.
With Teensy 4.0 what is the correct pin to use?
My goal is to extend the Teensy 4 Audio board's 3.5mm stereo output jack into a dual analog / digital jack using a mini Toslink format plug that is also 3.5mm. (Google did this in their Chromecast Audio device).
