The Plex experience with this TV (QN65Q70AAFXZC) is really bad at the moment,  
The most problems I encounter are audio issues.

Note that theses issues does **not** happen on another LG tv and my other Samsung tv (UN43TU7000FXZC)

1- Transcoding audio (AC-3 Stereo) to AAC (seems to happens when the audio track is not the first one). I expect direct play here. **EDIT: CONFIRMED BY THE LOGS**  
Example of a mkv that does this :

> Audio #1  
> ID : 2  
> Format : E-AC-3  
> Format/Info : Enhanced AC-3  
> Commercial name : Dolby Digital Plus  
> Codec ID : A\_EAC3  
> Duration : 49 min 36 s  
> Bit rate mode : Constant  
> Bit rate : 640 kb/s  
> Channel(s) : 6 channels  
> Channel layout : L R C LFE Ls Rs  
> Sampling rate : 48.0 kHz  
> Frame rate : 31.250 FPS (1536 SPF)  
> Compression mode : Lossy  
> Stream size : 227 MiB (11%)  
> Language : English  
> Service kind : Complete Main  
> Default : No  
> Forced : No
> 
> Audio #2  
> ID : 3  
> Format : AC-3  
> Format/Info : Audio Coding 3  
> Commercial name : Dolby Digital  
> Codec ID : A\_AC3  
> Duration : 49 min 35 s  
> Bit rate mode : Constant  
> Bit rate : 192 kb/s  
> Channel(s) : 2 channels  
> Channel layout : L R  
> Sampling rate : 48.0 kHz  
> Frame rate : 31.250 FPS (1536 SPF)

> Stream size : 68.1 MiB (3%)  
> Language : French  
> Service kind : Complete Main  
> Default : Yes  
> Forced : No

2- Completely inaudible or corrupted audio with PCM:

Exemple no sound / corrupted for both tracks I think they are converted agin to AAC:

> Audio #1  
> ID : 2  
> Format : PCM  
> Format settings : Big / Signed  
> Codec ID : A\_PCM/INT/BIG  
> Duration : 2 h 6 min  
> Bit rate mode : Constant  
> Bit rate : 13.8 Mb/s  
> Channel(s) : 6 channels  
> Sampling rate : 96.0 kHz  
> Bit depth : 24 bits  
> Stream size : 12.2 GiB (38%)  
> Language : English  
> Default : Yes  
> Forced : No
> 
> Audio #2  
> ID : 3  
> Format : PCM  
> Format settings : Big / Signed  
> Codec ID : A\_PCM/INT/BIG  
> Duration : 2 h 6 min  
> Bit rate mode : Constant  
> Bit rate : 4 608 kb/s  
> Channel(s) : 2 channels  
> Sampling rate : 96.0 kHz  
> Bit depth : 24 bits  
> Stream size : 4.07 GiB (13%)  
> Language : English  
> Default : No  
> Forced : No
> 
> Text  
> ID : 4  
> Format : PGS  
> Muxing mode : zlib  
> Codec ID : S\_HDMV/PGS  
> Codec ID/Info : Picture based subtitle format used on BDs/HD-DVDs  
> Language : English  
> Default : Yes  
> Forced : No

3- FLAC audio file with no sound

Example this file is not playing any sound:

> Audio  
> Format : FLAC  
> Format/Info : Free Lossless Audio Codec  
> Duration : 5 min 35 s  
> Bit rate mode : Variable  
> Bit rate : 5 588 kb/s  
> Channel(s) : 2 channels  
> Channel layout : L R  
> Sampling rate : 192 kHz  
> Bit depth : 24 bits  
> Compression mode : Lossless  
> Stream size : 223 MiB (100%)  
> Writing library : ProStudioMasters

I think every time when I look at the server it is always trying to convert to AAC while most of the file should be able to direct play. At least they do on my most cheaper Samsung TV.

Could you provide some logs, and a sample clip that reproduces the issue? I’m not seeing issues on my TV.

You must select the French language.

On 2021 Samsung TVs, audio track selection doesn’t work. We have to select the audio stream via the server so we have to remux. AC3 audio played over DASH that isn’t direct played also has issues with audio skipping, so it needs to be transcoded to AAC, so that’s why you’re seeing audio being transcoded here.

Do you have samples of the PCM or FLAC issues?

I see, that’s disappointing of Samsung. Have any idea if it’s a bug from the 2021 model or they just simply does not want to support that?  
Also sometimes, when the audio is translated to AAC, its out of sync, I must go back or quit plex and resume to make it in sync again.

For the PCM and FLAC I’ll make you some sample soon.

Edit: here is the PCM sample. FLAC will follow later it’s a little bit more complicated for me to create the sample.
