My dac (XMOS PCM5102) worked perfectly with version 1.4 on the UDOO quad excepting the problems already listed at the time. I was happy and looking forward to the upgrades. After downloading 1.5 when it was first released the x 20 driver did not produce sound from the XMOS on any setting. Sadness throughout the land. Recently I downloaded 1.5 again as a “what the hell” and found the X20 gone from the list and now was a “nothing selected” blank. Obviously a problem you recognise exists. In next incarnation please include x20 or similar for the little people who want to progress beyond 1.4.
Generally this player is far beyond the usual hi-fi gear. Excellent work!
