It's not against the rules to post it here, but personally I would call it a development discussion, which has an own sub-forum.
Nope. Copy&Paste from the forum descriptions:
Development > General help for development and building with LibreELEC
Bug Reports > If you found a bug and can provide a technical description of it, post a report here
I'm not searching for workarounds, I'm not developing or building LibreELEC, I report a bug.
And now lets please stop the meta-discussion and focus on topic

Development builds usually have bugs. You can use a stable built.
Sure, and that's what I'm already doing.
This forum is named "Bug Reports", and that's what I did: report a bug.

yes, dtoverlay=hifiberry-dacplus
It's all on the same hardware and config.txt: using Kodi's upgrade function I've been booting millhouse build #0116 , which is ok but #0117 not. Up- and downgrade and vice versa reproduces the problem.

ok, so I narrowed it down, last working kernel was 5.4.11:

Hi,
running on Raspi3, hifiberry can't be loaded in kernel 5.4.18, it fails with snd-rpi-hifiberry-dacplus soc:sound: ASoC: failed to init link HiFiBerry DAC+: -517

It's not an hardware issue, hifiberry is fine when booting a different image/sd card (see hifiberry_ok.txt for log excerpts).

Resurrecting this thread to share my solution:
The Fire TV Stick Remote enters some kind of standby mode, which disconnects it. My (not very elegant) solution was to try every 15 seconds from the RPi to reconnect:
1. go to libreelec bluetooth settings and (re)connect the remote
2. ssh to the RPi
3. issue command echo|bluetoothctl , write down the MAC address of "Amazon Fire TV Remote", for example 11:22:33:44:55:66 (yours will of course differ!)
4. create cronjobs to try to connect every 15 seconds:
crontab -e, enter in editor:
Bash* * * * * sleep 00;echo 'connect 11:22:33:44:55:66'|bluetoothctl > /dev/null 2>&1 * * * * * sleep 15;echo 'connect 11:22:33:44:55:66'|bluetoothctl > /dev/null 2>&1 * * * * * sleep 30;echo 'connect 11:22:33:44:55:66'|bluetoothctl > /dev/null 2>&1 * * * * * sleep 45;echo 'connect 11:22:33:44:55:66'|bluetoothctl > /dev/null 2>&1save and quit editor
5. Press the "Home" button on the remote for at least 16 seconds
6. Enjoy reconnected remote
Exercise left for the impatient: more cronjobs, less sleep
