Lightning device is too busy to process the required operation of the file, this will mostly happen with you have enabled the Resampler to convert the DSD file to PCM and also use WiFi connection. An unstable WiFi connection will increase the CPU load as Lightning device may not be able to receive the music data correctly and require a re-send of the data from server side. Such operation may increase the chance to over load the processor.
- Consider to purchase a recommended WiFi router by AURALiC or switch to wired (Ethernet) connection.
- Move current WiFi router to a place closer to your Lightning device and music storage device (if connected through WiFi).
