Hi eriv, yes I've got all the peripherals, Keyboard and mouse. I'm trying to minimize or remove as many variables as I can, to locate this issue. I'm also able as you suggested, to use Gizmo, EOS, JRemote and JRemote2 to play audio to my phone (WiFi or Cell) without any errors. But using above mentioned to play to the Oppo, well, the audio stops shortly after it starts. And of course the main reason to hook up with the Oppo, is the great sound the DAC creates in my home audio system. Similarly I should point out, I have a Surface with Windows 10 w/special ASIO drivers and that plays all the audio flawlessly. I just hate tying up that piece of equipment as a media player, so that's where the RPi comes in.
