Why does my D1P indicator light change colors?

Audio formats and bitrates are shown by the color of the indicator light on the D1P

White   PCM 32-48kHz

Green   PCM 88.2-192kHz, DSD64, Optical

Blue      PCM 352.8-384kHz, DSD128

Purple  MQA Rendering

*When connected to a Mac or PC, the indicator light reflects what your system sound audio output quality is set to, not the bitrate of the specific track you’re playing.
