Starting from Volumio 2.348, a new improved USB driver is included on the Sparky image, which will fix a problem with some USB DACs (no sound output).
If your DAC (such as the Dragonfly) produces no sound, do this to fix it:
- Enable SSH volumio.github.io/docs/User_Manual/SSH.html
- Execute this command :
sudo nano /boot/uenv.txt
- Locate the line
and change it to
If you can’t find such line, just add it.
- Save with ctrl and x
