Good afternoon, I installed your assembly on the Charry trail netbook Intel Atom X8350, everything works except for sound, aplay -l view and HDMI and chtnau8824, kodi sees it too, but the sound does not go through the code or from the console, ucm files are available, on ubuntu 19.04 the sound works immediately, through alsamixer I see the settings and sound levels, but there is no sound itself.There are some additional sound modules on ubuntu, but they are not in Libreelec. and I can not find them in linux.x86_64.conf
Well does it work with any stock/vanilla LE version? If not it's a matter of LE and not really for this build only. So please check this first and if it doesn't work in other LE builds e.g. libreelec-generic.x86_64-9.1.501.img.gz then it has to solved upstream.
Btw. to generate nice logs just enter your command whatever args | paste and you'll get a link which contains the output. And while your at it read the start post again how to grab the logfile.zip and post it here.
