LG webOS25 Movies with Flac multichannel audio

[julianlocal 1]

I bought a new TV and found out on WebOS25 LG started to remove the Flac support on movies. So when I want to play a movie with 5.1 or even 7.1 audio it only plays some rare parts of music/ nothing. On my old LG TV (from 2020 and 2021 with the older Web OS) it works perfectly fine. 
Movies with "only" 2.0 Flac audio are still working perfectly fine. 

It would be very cool if that could be made working again. If more details are required, testing is needed that wouldn't be a problem!

My EMBY Server is running on a Windows Server and it is up to date (V.4.9.1.90) and it is definitely not the movie(s) on every other device (including my older LG WebOS TV) it is running perfectly fine. 

 

PS: Not sure if it is a bug or a feature I request, since it is a mix of both. Hope it is correct and Merry Christmas everyone

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

Sorry, I do not have much time at the moment.. 
I can tell you it is not on that LG it is also on the LG OLED's from 2019 that use an older version. 
I found a temporary to fix it, I enabled playback options and limited the bitrate so my server has to transcode it.

If I have more time what is meant by an example? Like demonstrating it with a movie? 

EDIT: It is weird, but on the TVs from 2019 the voices can heard just extremly silent, if I switch to 2.0 Flac audio or use the "temporary" fix I wrote about it is normal. On my pc as with the original file as with emby it is completly normal. Normally especially on the newer WebOS25 tv, I only hear the background music/ some music parts.. it seems like the TV can not really deal anymore with the audio at all. No matter if I try to play the movie with DLNA over the integrated media player or with the emby application. When I play it with the emby app over miracast or airplay it works completly fine.

OK yes it sounds like the TV isn't handling multi-channel flac very well.

I'm personally not sure, if that is something the emby can fix, a workaround (that works already now, with limiting the bandwith emby is allowed to use), would be something that needs to be configurable per user.
E.g. in my case:
user: Smart-TV
Has to transcode: Enabled -> Format: XYZ
What surprises me is that noone else experienced it like this so far, with emby (that mkv files with flac multichannel audio makes problems was something I read in context with the integretated media player, what I noticed when reading this forum in general LG seems to make a lot of problems. 
I mean not sure what's needed now to investigate that issue, if there's something needed/ needs to be tested now I have more time for that.

The app has options to force transcoding for certain formats. We can add flac to that list.

Yeah that would be enough, because I think fixing that issue would be a long and hard way to get around this
