Hi All,
I have this tv: https://www.lg.com/it/tv/lg-OLED55C8PLA-tv-oled
I have the Sonos Beam connected through HDMI ARC.
I have an external HDD connected in USB and i want to play .mkv movie with this audio:

My TV, from technical specs is able to Decode DTS Audio.

Thank You

No - the HDMI will pass through DTS which the Beam can not decode. I believe the TV will convert DTS to PCM by setting sound output to PCM - but you will then loose surround (stereo only).

But, if the TV is able to decode DTS by his own, then it should be able to pass at least Dolby 5.1 through HDMI, no? I mean, is the same thing that a PS4 or Xbox One are able to do, but the TV will do it.
+22According to owners manual it passes all day as dts. It can decode dts but can’t transcode to another format. Manual says dts to dts or set tv to pcm only.
Ok, so what do you suggest if I want to get max quality from dts to sonos? Do I have to buy some external devices to put between tv and sonos?
You can convert the audio track from the MKV files to AC3 codec (Dolby Digital 5.1) to make it work with the Sonos Beam.
To do so, you'll need ffmpeg from here: https://ffmpeg.zeranoe.com/builds/
Create a new BAT or CMD file (for example `audioConvert.cmd`) in the same folder as `ffmpeg.exe`. Paste the following in the new BAT/CMD file:
This script copies all video and subtitle tracks and converts the first audio track (and dismisses other audio tracks). Drag-drop a MKV file on top of the script or call it from the command line. A new copy will be created with the same filename + `-AC3.mkv` suffix.
