I set up an RPi 4 with Gentooplayer and Audirvana Studio Linux and sent it to a friend. It worked perfectly for me. He has it connected to a wifi-to-ethernet adapter in his listening room. He has Audirvana Studio on his Windows laptop, and it will see the RPi as a renderer and plays just fine. He can also use Audirvana Remote on his iPad, and it syncs with the laptop and controls it. But when we try to use Audirvana Linux on the RPi, his iPad just keeps asking for the login over and and over and will not sync with the RPi. Does anyone know what the problem might be?
