Am running RoonServer 1.2 on a dedicated Ubuntu 16.04LTS machine (all updates installed). No other apps installed or running. Am controlling via a Macbook.
In audio setup I can configure SPDIF output to my Benchmark DAC2 with no problem. I can also see and configure USB output to it (“Benchmark DAC2 USB Audio 2.0”) - apparently without a problem.
However when I play anything to the DAC via USB all selected music titles rapidly cycle past in the UI and there is no sound. The lights on the DAC also do not indicate any signal is being recieved. Via SPDIF everything works normally. Output to the DAC via USB also works without a glitch from my Macbook
I am a bit stumped.
aplay -l gives:

My guess is something isn’t right in the server but my Linux skills are limited and I’m stumped.
Any ideas?
