Do you have a screen on your RPi4? I never had this issue before I got the screen. I’m running RoPieeeXL.
No screen. I just use my iphone as a remote.
It is and nearly deafend my several times. Roon have also contacted them to say it’s an issue. The screen has got nothing to do with it as I don’t use any and it’s happend on Ropieee and Rock. It’s fine on windows.
