FWIW -
Roon running on MacOS (Catalina 10.15.7 - 2012 4xCore i7 @ 2GHz), ethernet-connected
HiFiBerry on R-Pi 4 with Volumio (NOT HiFiBerry OS), ethernet-connecetd
Pi hooked via USB to a Schiit DAC and thence to Schiit headphone amp
Works fine, just like the other end points
Volumio:in general playback options, I have I2S DAC turned on
I have HiFiBerry Digi+ Pro selected as DAC Model
Also note that this setup worked fine at one point. I can’t say exactly when it stopped working as I was not using this device for a period of two weeks. I just know it worked before that and didn’t after.
I am so sorry that we’ve missed your post for this long. I apologize for the delay
