Hello, I bought U1 few days ago, installed LibreELEC on SD card. Everything looks fine, HD audio passthrough working, smooth playback... I am using Logitech Harmony 650 infra red controller. Original remote for U1 has very few buttons only, it's basically just arrows/OK/back. Is there any way to learn Harmony additional buttons, like "pause" or "subtitle delay +" and so on ? I know about CEC, but my U1 is connected to Onkyo TX NR-609 receiver, not to TV directly. Thanx a lot.
