So I've received my lovely new raspberry pi 4 and it works ok ish with libreelec. But unfortunately I can't get it to work with volumio. I'm hoping that there will be an update for pi 4 because it is so much better (hardware) than pi3. The ethernet is not via USB anymore and the USB hub is better ( usb3) and hopefully not so noisy. Using kodi on it wasn't perfect but my god it was fast.
