Teensy 4.0 Arduino sketchy for TOSLINK (SPDIF) Input -> USB + SPDIF Output
// Teensy Library to stream Optical TOSLINK input simultaenously to two outputs:
// * USB Audio
// * SPDIF
//
//
// Test Setup:
// * Input: Google Chromecast Audio TOSLINK Optical @ 48 KHz -> PLR135/T10 -> Teensy SPDIF_IN
// * INput: USB serial console to set gain
// * Output: Teensy SPDIF_OUT -> Khadas Tone Board RCA SPDIF input -> Analog Speaker Amp
// * Output: USB -> Arch Linux (5.10 kernel) with Pulseaudio + Audacity
