It might be an issue with the CMA value in device-tree being too high. I force it to 896MB to facilitate 4K playback but this fails gracefully to 256MB on devices with under 2GB RAM. However, unless it accidentally works with the 512MB version of LaFritte I have no plans to support it. We have the same position with numerous 512MB Allwinner boards. Our experience with them (and older Raspberry Pi devices) is that 512MB is no longer enough for reliable Kodi use and our resources are limited so "pick your battles" applies.

Hi. I searched for this "CMA" value text string in your repo, file linux/meson-gxl-s805x-libretech-ac.dts at master · chewitt/linux · GitHub but nothing with exactly that name doesnt exist. Can you give me a bit more information where to put necessary changes to recompile Libreelec Master for this specific version 512 Mb/LaFrite. i want only play 1080p hevc/h.264 dvb channels on this board.

Hi. I have also 512MB version LaFrite and i have the same situation for HDMI out as described by @davisonja

this image from test don't have proper support for this board version /512MB

LibreELEC-AMLGX.arm-9.80-devel-20200314152345-6c08564-lafrite.img.gz

maybe it's just dtb , in oryginal libretech linux dtb for this board ~36kb , in Libreelec tree ~25kb.

Any sugestion how to resolve this error for this board?

likely its the same that does not build with latest kernels, he wanted to push a fix for it soon so it should be doable soon

this patchset have only one "Warrning" when compile media_build from linuxtv and works

Ubuntu-media-tree-kernel-builder/patches/mainline-extra/tip/80.montage.3103b at master · b-rad-NDi/Ubuntu-media-tree-kernel-builder · GitHub try this, if 3103b devices included works with upstream media_build you can create additional pack for testing dvb drivers something like "media_build from upstram + occasional patches"

Depending on the Bluetooth latency, this may sound pretty poor.

I think this delay to rear speakers conected trought bluetooth in hundred milliseconds could be customizable by individual user needs , sended little time before video stream with rest audio appearing on screen, I think some additional muxing in maybe "player core ?" with cache/buffer could be the way to realize that...

For this solution to complete users complicated setups I also propose to add "upnp audio stream input" and "upnp audio stream output" over LAN for audio setup /multichannel if possible.This will be helpfull for example if you have back placed cinema projector with 2nd installation on tv box or sbc,htpc etc or to route audio from another upnp enabled for sending over upnp audio stream pc smartphone etc...

HI , i'm not expert with pulseaudio framework but i think this could be possible,,,

1. HDMI output to TV configured as center speaker/channel.

2. Analog/Spdif onboard audio out as Front L/R channels virtually 2.1 depend on speakers setup

3. Bluetóoth A2DP Sink as Rear L/R channels

This will create 5.0/5.1 speaker configuration.

I don't know how to write config for pulseaudio and i don't know if this is be accepted by Libreelec subsystems and don't provide errors in menu/settings/audio.

here is patch for 3103b for upstream kernel Linux V4L/DVB mailing list - Patchwork

for my device "terratec cinergy S2 rev.4" drivers included in this ubuntu repository working perfect

Ubuntu kernel + LinuxTV media tree + Hauppauge patches : Brad Love also should be working for technotrend tt-connect s2-4600 with 3103b chip version, maybe others too...
