Yes
While using PMS on VLC-network I am able to find the folder within series but I am not able to find folders within other content
BTW:
Forgot the FireTV-stick which must be in the Hardware-setup, too!
So two questions …
a) this way = ?
NAS → Shield → Soundbar
AND
FIRETVSTICK → Soundbar
AND
Soundbar → HDMI ARC → TV
OR
b) this way = ?
NAS → Shield → Soundbar → HDMI ARC → TV
AND
FIRETVSTICK → TV
a) or b) would be best solution?
VLC is powerful app
VLC sees all your devices in the LAN but before you need open FTP or Samba on your NAS
regarding connection of soundbar there are a lot possibility and you can try each and choose you like
I agree, but I’m not sure that using the app in troubleshooting a problem with Plex is the best method. VLC will play almost anything, in any format, and doesn’t necessarily rely on the capabilities of the device. Plex apps do, as well as the capabilities of the server. Taking the time to get VLC working (enabling DLNA, FTP, Samba, etc) will not likely fix the problem from the OP. is having with Plex. 
I would start by getting the properties of the files being played, (audio and video codecs, subtitles enabled, type of subtitles, etc) and go from there. The server has transcoding disabled, so any combination of subtitles, audio formats, video formats may require transcoding for the app. If the server isn’t powerful enough to transcode (and/or it’s disabled) the file just isn’t going to play.
@DESASTER75 - does the Firestick see the plex server, and work as expected? That was not mentioned originally.
yes i agree with you but I can not receive from him any answer regarding transcode reason (video or audio/subtitles)
I use VLC only the way to check speed connections and files accessible
Stick and TV do both have full access to 100% of content but both do have buffering-issues.
I would like to stop all that handling! I only would like to get content to be played in GERMAN without any subs, …
check did you switch off the subtitiles
Probably a silly question… in Plex Web → Settings → Account do you have the language configured to German? Particularly under the preferred audio and subtitle languages.
I have mine set this way (for English) All apps automatically select my language choice, and only use subtitles when the audio is in a different language. If there is not an audio stream in my language, subtitles are automatically enabled.
… of course I did 
Do I have to switch some of those options off (or remain on)?
Do I have to swithc some of those options on (or remain off)?
Do I have to swith on the IPv6-compatibility-option if I am only talking about local usage of PLEX-server?
There is no option to switch off ‘subtitels’ at all! → Where is it?
There is only an optoin to let PLEX-server automatically pick subs as picked in the drop-down-menue below that option …
this is not here!!!
if you need those screenshots while using ENGLISCH no prob - could switch language - just let me know
Where is it? → options of contend-library?
Hi
ALL options where I am able to pick GERMAN are set to GERMAN
unmark Automatically select
and try to play
Hi, is and never was set to ‘automatically’!
try to play file and make screenshot of Dashboard
and
Subtitle mode must be Manual select

… while using TV-PLEX-app
OR

OR
… while using VLC
I guess you are talking about first option, aren’t you?
