I am having intermittent drop out issues since upgrading to 1.3. Sonictransporter I5, Microrendu, USB connection to Metrum DAC. When the dropouts occur the status LED on the DAC blinks indicating loss of connection. Never a problem prior to upgrade to 1.3.
Can you check Settings > Library and confirm that audio analysis has completed?
Finally, can you give this guide a read and let me know if any of the suggestions are helpful here? We can absolutely look into this further for you, but I want to rule out basics first.
