A bit late to this party, but I was unable to get picoreplayer to run on a new RPi4 / HiFiBerry Digi+. It never connected to my network by wireless or wired ethernet, my router did not show it as a connected device. Makes headless control difficult, and it did not drive a directly connected display at all.
Moode works fine, but IIRC I had to have a display, mouse and keyboard connected to it initially to set up a wireless connection. In fact, I can use Moode with a mouse and a TV as a display for direct control, no PC or network needed.
As noted in post #5.... this is how you get the locally attached HDMI display to show MoOde ..
Raspberry Pi4b 4GB 6.4.0 - gray screen after "Reached Login" text
i don't know Drone7, I tried http:// moode and moode.local and also IP address, none worked, funny thing is that the PC found hifiberry.local straight away.
The system is Pi 4, 16Gb sd card, Hifiberry os, ethernet connected to router, HDMI to screen, PC also connected to router and separate port on the screen.
I loaded Roon on the PC today, Roon tells me it's accessing the Hifiberry via airplay so I finally got to play some music through the 'berry'. Hopefully it is working like it should and not taking the PC as a source.
That's great news! A bit of a personal situation is going to keep me from playing for a few days. But I'll get back this weekend.
So a quick update, system is working fine now. I'm playing around with Internet radio 'till I decide on either Qobuz or Tidal. Thanks everyone for your helpful advice and suggestions.
