Volumio on Tinkerboard and USB audio - dragonfly

Hi all,

Have Volumio setup and working on a new ASUS Tinkerboard.

I can only get audio out working on the audio jack.

I have an Audioquest Dragonfly USB DAC and when plugged in Volumio recognises, I can select it in audio output settings, but no volume. I have also tried setting Volume Control to software and also none and still no sound out …

Has anyone else with this combo had this issue or solved it?

OR is this a kernal or Volumio Audio driver issue?

Many thanks in advance.
