The black screen on boot issue is now resolved on the test build. From good things:
* DTS pass-through seems to be working fine with my Yamaha AVR.
* The overal UI and video playback seems to be more smooth (compared to the Raybuntu's release from couple of months back).
Next problem:
* Cannot add the Docker addon (no where to be found). I need to add other home services here (openHAB, syncthing)
* Also going into Addons > Browse Repositories > LibreELEC Repository gives some error and shortly after entire OS reboots
