I think it will be difficult to support this HW.
What I found:
- Running on a CM4
- Audio is USB or HDMI
Questions:
- According to the site it’s not delivered with Volumio, So I expect you flashed it yourself?
- Please elaborate what you mean with no output?
- Which version of Volumio is running on that device?
- If it boots, please provide a log.
- You did install the plugin “Roon Bridge”?
