No sound in Dolby digital

Hello Forum,

i have the following problem with my plex server. All movies are not played in Dolby Digital or DTS.
I am streaming from my Synology Server (where I have a lot of movies stored, all at least Dolby Digital or DTS) to my Panasonic OLED EZW950 TV. There I look at the installed Plex app. The TV is connected to my Yamaha DSP A2 surround amplifier via an optical cable. When I watch Netflix or Amazon Prime, or movies via satellite on the TV using the built-in app, the Dolby Digital signals are cleanly transmitted to the amplifier and also output. Only with the Plex app I can’t receive Dolby Digital.

What am I doing wrong?

Thanks a lot!!!
Stefan

thank you in advance for your answers.

My TV is a Pansonic EZ950 OLED with 65 inch from 2017, bought in Germany.

What is an AVR? I connected my TV with my Yamaha DSP A1 only with the fibre Optic cable, because my Yamaha is too old and has no HDMI Port.

I put the log files attached in my email and also one more log file – if you need.

But i can’t put that XML file, because the window is empty. I tried it with several films – all the same. But most of my films do have 5.1 Dolby digital or DTS.

Now I took another look into the settings of the Plex App on my TV. Under sound settings I have to select Dolby Digital and DTS. But! when I select these options, I don’t hear any sound at all. So the two options are always disabled to hear any sound at all. This is probably the cause of my problem.

Thank you Trumpy82 for your help!

Best regards Stefan

In the android Tv app there is an audio passthrough option, go to settings and scroll a bit down. Set it to Optical.

Sorry, I thought the Panasonic was an android device. My bad.

Hi Everybody and thank you for your answers.
Now i rent a HiMedia Q10 Pro Media-Player from a friend and i installed the plex app. So far so good. Now i can hear Dolby Digital 5.1 sound. But when i changed the audio settings in DTS - there is nothing to hear. No sound at all. When i play the same movie by the intern media player the DTS sound is perfect.
I send the files from Plex once more with this chat.

Thank you in advise.

Hi Trumpy,

many thanks for your answer.

Have you carried out my previous instructions and moved your media etc.?
No, sorry i forgot these. A friend helped me to configure Plex on my Synology server. But i hope i can carry out the files in the correct directory. :thinking: :flushed:

What do you mean by changing the audio settings in DTS?
My MKV video files have 2 audio codecs with which I can play the movie. Dolby Digital and DTS. I can specify this in the menu of the audio output in Plex.

Does this Himedia player have a Plex app installed?
Yes i installed it on the HiMedia Q10 Pro. Dolby Digital is working and DTS output not…

Thank you Stefan

Hi Trumpy,

maybe i’m blind, but i didn’t see the warning Message… :frowning_face:
and i’m not sure what exactly i have to do. All the media is stored in one folder called “Plex”. Or do i have to move out all the media in an other folder on the synology server?
Thank you!!

Hello Trumpy thank you for your so excellent description.
I did it now, and after some try and error - everything is going well. Only some music descriptions and covers i have to reorganize. Now the Plex folder is empty only there are two folders left: Library and tmp_trancoding. My other folders are now in a separate folder. But i think it is ok not to have these 5 folders. ```
Movies
Music
Other Videos
Photos
TV Shows

I have now
2 Movie Folders (1 folder for movies over 16 and one for the children)
and also 2 Folders for other videos 
1 music
1 Fotos
1 TV Shows ("Serien" in German language)

So thank you for your good help!!!!!

Stefan
