I am using LibreELEC-S912.arm-126.96.36.199.force.444.10bit.tar from wrxtasy (Releases · wrxtasy/LibreELEC.tv · GitHub) on a Minix U9-H and it works very well, although there is an issue with HDMI/CEC.
I have the Minix connected to the TV (LG Oled E6) and from the TV to AVR (Denon AVR-1912 through ARC).
Without the Minix/LE, the TV and AVR are "CEC linked" and working fine (that is, turn TV on => turn AVR on and change volume on the TV => change volume on the AVR).
However with the Minix& LE plugged to the TV, there are issues with HDMI/CEC; whatever I do (enable/disable CEC service in Kodi, put the Minix into sleep mode, etc.):
- when LE boots, the TV switches to the Minix every time
- if the Minix is not up and running, sound does not go out from TV to the AVR (even from the TV itself, it remains silent)
It is as if the HDMI connection was hijacked by LE and from that point everything was under LE control, but a kind of "wacky" control.
It is sometimes so annoying that I unplug the Minix & have turn the TV & AVR to off then on again to have a "normal" working TV and CEC chain.
I guess it might be an issue between LE and LG TVs, as there have been reported issues with libCEC:
==> what version of libCEC is used in that LE release? Maybe the problem lies there?
