I am running the latest version of Roon, along with the latest version of HQ player. I have added a new Ross Martin DAC via USB and it started out working fine, now Roon will not play. It still recognizes my library, but the cursor is red and the playback will not start. I have run disk first aid, and the DAC works fine playing back Youtube files. I really need an answer, as I am dead in the water with my music library.
