I join this group just to post this. I just bought the Douk Audio U2 Pro. USB Digital Interface, The fiber output stop working after the unit had warmed up. Douk Audio would not let me return the unit. They started to play email games with me asking if I updated the drivers and if other outputs are working. When I need only the fiber port working. I run a imac and no other drivers needed.
My background had been in electronics all my working life. So I know if something is not working the way it should. The stop emailing me when I told them what was going on with the unit.
