Addon was not build even today because I made a mistake in it. I hope it will be available tomorrow.

Hi, I have a question… I bought a LG SP9YA soundbar which has Dolby Atmos and DTS support. I use the Homatics r 4k plus box (Coreelec) and I have it connected to an LG Oled C1 TV, which unfortunately does not support DTS sound. I have the soundbar and TV connected via HDMI ARC. However, a lot of streams and films have a DTS track or even only DTS, so I would like to ask if it is possible to somehow use the DTS audio pass-through so that it is full-featured? For example, I tried using an optical cable to connect the android box to the soundbar, but I couldn’t get the sound to work (it always said something like unsupported format). Does anyone have any advice on how to play DTS sound using an android box via kodi, which will run the picture on the TV so that the sound goes through the soundbar that allows dts? Thank you in advance for your help.
Have you got passthrough and earc on the tv enabled? Or you can set kodi to transcode dts. Most streaming stuff i see is atmos or ddp5.1.
It looks like I didn’t have audio pass-through on the tv… And in kodi’s pass-through settings, I turned off DTS formats and now it’s running, it looks good.

Your only affordable option to get all DTS sound formats is to use an HDMI Splitter, something like this
The other option is to get a TV that does support DTS audio formats 
Hello, I want to buy this box Heomatics Box because for this money it seems to be the best Is there anything better for this money?
Hello. I have a question. Can CoreElec on Homatics play image and sound encoded in imax?
So, because words are hard, I think I screwed up the install on my Dune.
I cannot get DV to work at all and rereading it all again I think where I went wrong is I didn’t grab the nightly version of Nexus and did the 20.2 stable. Because again, words are hard, apparently.
My question is: Is there any easy path to upgrade to a working, DV enabled nightly that doesn’t involve rewriting the USB stick? I did a lot of configuration already which would be easy enough to reproduce, but if there’s a “oh yeah, just do this” answer then that would be grand.
Also, I’m getting some buffering on 4K content. Does anyone have known good values for cache settings in the advancedsettings.xml?
Thanks!
Imax format is just screen ratio and sound (in dts hdma 5.1) and when encoded to mkv file, it just like others, so there is nothing relate to CE here.
Yep, LG C1 refuses to passthrough anything related to DTS.
When you turned off DTS passthrough in Kodi, I think DTS is converted and output as dolby digital.
If you’re fine with having just the basic formats (dolby digital and DTS), connecting the soundbar with an optical cable should work, you just have to select another audio output device in Kodi (the name of the audio device has something about “SPDIF” in it, I think) - but this way you won’t get HD audio formats passthrough (dolby trueHD, DTS HD MA).
If the soundbar does not have separate HDMI input (for Homatics device) and output (to the TV) connections, then probably the HDMI splitter is the only way for all audio formats to reach your soundbar unconverted.
service.homatics-leds addon is now available in CoreELEC repository 
Without knowing what you were doing it is hard to tell what is wrong. DV should just work and there is no special trick to get it working. Post debug logs.

The soundbar has 2x HDMI 1x HDMI IN and 1x HDMI OUT, if I connect the homatics box via hdmi to the HDMI IN of the soundbar and from the soundbar via HDMI OUT I run the second cable to the HDMI ARC in the TV and enable the pass trough in the TV, should it work as it should? I haven’t tried this or it didn’t occur to me 
Just put the CE-ne nighlys tar file to your update folder, after the update, the DV will working.
For advancedsettings, maybe try use this values.

I think it should work the best when connected this way, regarding sound transmission from CoreELEC to the soundbar. The soundbar should be able to receive the most audio formats in their original quality this way.
Unless the soundbar is not able to passthrough all video formats to the tv, I think this way to connect things should be best for you. The only drawback (if you would consider this a drawback) I can think of in this setup, would be that you must always turn on the soundbar when using CoreELEC. And even that might not be the case if the soundbar may passthrough the HDMI signal to tv in standby mode.

@vpeter I thought what I did wrong was installing 20.2 stable instead of a nightly build of Nexus. Are you saying it should be working in 20.2 stable?
Thanks! I will try both these suggestions.
Do not use the stable version if you want Dolby Vision with CoreELEC on Dune Homatics, use the latest Nigthly, 20231116.
Yes you should use passthrough with the soundbar, HDMI in > out to TV. No need for any passthrough setting on TV, that is just used for displaying with this connection.
Hello.
I had CoreElec 21 installed on a pendrive. I updated Android TV to version 12. I think I also updated CoreElec to the latest version then. Then I switched to Android TV and didn’t use CoreElec for a long time. Currently, CoreElec does not boot after restarting homatics. I do not know what happened. I have boot from USB set in Android TV settings. Anyone have an idea?
I don’t want to re-upload CoreElec unless I have to.
Ok, I’m starting to feel like age is getting to me…
But how do we install the led addon? 
I must have missed it in on coreELEC repository > services, on my coreELEC install on dune.
