My new DAC Pro-Ject USB S BOX DAC does not recognize my Volumio RaspberryPi 3(A).
Blue search-light on DAC flickers, like it’s not finding anything to connect to. But the Pi seems to feel the DAC…
According to the compabillity list the DAC pairs with P2:

The VolumioRaspberryPi 3 plays well without the DAC using the Audio Jack.
The DAC also works fine with Ubuntu 16.04 LTS and Winders.
The mpd.conf describes:

I suspect the problem to be the ”hw:5,0” here. My suspicion is that it’s not configured enough? Any ideas or help would be most welcome…
