Sounds like just my problem. However, my Amp2 is mounted on a Pi4. Max2Play version is the latest 2.50 beta for the Pi4.
I have a screenshot, but it seems like I can’t upload images.
Unfortunately I can’t report what happens after removing the Amp2 board, since I don’t have a fitting AC adapter (whole device is powered via Amp2 like it should be).
For me, I’m 100% new to Max2Play so everything is still at the default settings. There’s no physical LAN cable attached, and I never configured any kind of Wifi connection.
