Volume not working from Roon

[BlackJack]

The volume works from the Pro-Ject streambox app but not from Roon.

Check volume options in your bridge.

I’ve noticed that Roon does not recognize my DAC but does recognize “Roon ready streambox” as a bridge.

This is correct. Your DAC is neither RoonReady nor RoonTested. Roon wil play to your DAC nonetheless.
