Hello,
An update. I tested with these approaches below (clean installation and correct configuration in Roon, so extension enabled):
-
Display with power coming from a separate adapter. The display is black after these messages (apologies for the poor quality, you should be able to read the latest info messages)
-
I removed the HiFiBerry Digi2 Pro V2.2 after shutting down everything and the display works now taking the power from the Pi Rasp 4, like in the guide, and it worked.
Now, questions:
-
Is the HiFiBerry Digi2 Pro V2.2 compatible with this Ropieee version (ropieeexl_ose_pi4-2025.5.0-stable.20250518.2453)? It seems not…why the Ropieee would not be able to action the display (powered independently) with the hat on top of the rasp 4 and why would it work without it?
-
My DAC (D50 III) should be able to receive the audio output from the USB (which one 3.0 or 2.0 from the Pi Rasp 4 is better?)
I must have the output via optical cable because TV and Streamer will be used this connection and will go to the DAC via automatic splitter. The DAC is not switching channels automatically so it will negatively affect the final experience if I can’t use the HiFiBerry Digi2 Pro V2.2 hat (which it seemed to be compatible with Ropieee)
Thanks in advance for your patience.
