Hi grhhm!

I don't know your complete setup, but I think you're on the right track.

To call a TV RC power button script, you could wite something like that at /storage/.kodi/userdata/keymaps/remote.xml:

<keymap>
  <global>
    <remote>
      <power>RunScript(/full/path/to/your/python/script)</power>
    </remote>
  </global>
</keymap>

Test this mapping by scripting a simple task, like creating a file.

If your TV backlight RC power button acts the same way like the TV RC power button, then you probably don't need a variable for the on/off status. Acting the same way means, both devices only have one RC button for turning on and off.

Maybe the LIRC solution of Hias is better, but it's good to have extra options.

Connect an IR sending LED with the RPi and send the fitting IR code to the TV backlight.

Installation instructions about IR sending LED on RPi GPIO are available on the net.

This sending process will be triggered when the RPi receives the "TV Power" button press over CEC.

You can use LE's key mapping to start your script by "TV Power" button press.

The RPi "knows" whether "TV Power" on/off means TV backlight on or off by using a variable at your script.

Cheapest and easiest solution: Install a power button instead of using RC.

If you really want to turn it on by RC, then you definitely need additional electronic parts. There is no way to use an attached USB IR receiver after the RPi 4B has been turned off.

You could use an Arduino (or other micro controller) with an attached IR receiver, which:

• is permanently listening for the right IR code
• triggers RPi's GPIO 03 when it receives the right IR code to turn the RPi on

Problem: This micro controller has to be an always-on device. It just consumes less power then an RPi while it's on.

Code

config_hdmi_boos=7

According to the official config.txt documentation this option will be ignored on RPi 4B.

To increase HDMI signal strength, you could try a new cable. HDMI 2.0 and HDMI 2.1 standard cables are made for 4K. Get one of those.

This forum is not so important that it gets spamped. Too small community.

Well, it seems to be very important for Chinese spammers. Guess why...

I've seen many pages of pure spam here. Drastic protection is necessary.

Yes, the community is small, but high quality.

I have this low powered minipC and tried to install LibreELEC but no luck......... Any clues on what I need??

New thread please. This is only a buyers guide, not about precise installation instructions.

Android itself is highly optimized to play media. It's a perfect base to run Kodi. LE isn't the more performant base for Kodi.

On RPi with LE you can use your TV remote, so you don't need to buy that part.

You have to buy the RPi, a case and a PSU. All in all it still could be under 50$.

Here are my instructions to install a power button and a status LED: Instructions.

This will make it work like a commercial box. Don't fear to build it.

Sure you could buy a cheap Android box from China, install the Kodi app, and everything is fine. You really don't need LE as an extra OS.

Problem: You will run into a support problem after a couple of years. Those China boxes have blocked boot loaders, which makes it impossible to install other OS'es. When the China boys decide to stop software updates, then you can throw your box into the dumpster.

That's why we suggest open source software here - you will have support for a long time.

If you have an old PC, the Android X86 project is an option. I'm not sure whether RPi Android is already usable (young project), but I have been tested Android X86 successfully. In combination with the Kodi app this could be all you need.

Tigro :

The only tricky part of an RPi 4B could be Android dual-boot. If you like to switch microSD cards instead, then RPi fits for you.

Just thought I give libreelec a (new) try in the new year and same f*cking problem on both machines.

My RPi 3B+ runs fine with LE. Maybe an add-on problem on your side.

Start to be more practical in 2020, and read your log files.

You will not get a noob-friendly device for that price - you want the best of both worlds.

If you forget about the price, then the Nvidia Shield TV is the noob-friendly device #1. It runs Kodi (not LE) and Android perfectly.

If it has to be under 50$, then buy a Raspberry Pi 4B (sub-version: as much RAM as you can afford). You can dual-boot Android and LE on it.

What a crazy fix!

PS: Conclusion: HiFiBerry doesn't test the products they ship. That's bad.

There is a setting at /storage/.kodi/userdata/guisettings.xml:

<setting id="audiooutput.volumesteps" default="true">20</setting>

Reduce 20.

If you really can't get any audio from the card, blame HiFiBerry.They shipped the wrong device, so demand the right one and try again.

PS: If you decide to buy an RPi camera port device, then the add-on "Raspberry Pi Tools" should provide the driver for LE.

You can play around with audio volume / mute by directly editing guisettings.xml (top and bottom of the file).

PS: A little thing you should think about: Usually companies don't upgrade an ordered product without good reason. Maybe they shipped a Pro version, because they know the COAX output is broken, and they hope you only need TOSLINK.
