Plex Server Version#: 1.28.0 Plex Player Version#: Plex for LG, client 5.43.2, platform 7.1.0 Television Version#: LG OLED77G2PUA Receiver Version#: Onkyo TX-NR646 With DTS (DCA) on the client enabled, some media with DTS will not play, yet others will. I haven’t been able to figure out why. I h…

Current LG TVs do not decode or passthrough DTS audio formats (they dropped support several years ago). Check the specifications for the TV. DTS is not listed. The review at rtings.com provides further details. Do not check the box to enable DTS audio in the Plex LG app. The box is visible, but…

If you have a TV that still supports DTS, also check what type of DTS is in the file. There are many variations of DTS and your TV may not support all of them.

Thank you very much for this information. I don’t want the TV to process the audio at all and simply pass it to the Onkyo receiver. Since I have selected in the TV configuration to send audio to Optical out, I think that it is simply treating it like a passthru. Isn’t that correct? I assume that it…

Why are you using optical instead of HDMI-ARC? As mentioned in my first reply optical is much more limited than HDMI-ARC. No matter which connection you use, do not select DTS audio in the Plex app settings. I do not know why you hear audio for some DTS tracks. The TV may be converting it to ano…

I determined that the ones that are playing have a second track that is not DTS. Plex is likely choosing this to play. Unchecking the DTS (DCA) in Plex gets the audio to play for the ones that didn’t have a second track. Does Plex do a quick conversion from DTS to something else? If so, to what? Sho…

[image] esmathis: Does Plex do a quick conversion from DTS to something else? Yes. [image] esmathis: If so, to what? You should be able to see this in the Dashboard of the web app, during such a playback on the TV. [image] esmathis: Should I manually convert these files to AC3 or…

Thank you so much! The Dashboard says it is converting it to AAC. But, how many channels and what bit rate? It doesn’t show this. It seems to me that I should convert the DTS files to AC3 (5.1 channels, 448K) rather than AAC (5.1 channels, 384K) since AAC has a lower maximum bitrate. I’m using Box…

[image] esmathis: I’m using Box4 Movie Re-Packager and these are the best options available. XMedia Recode It can copy the video stream unaltered and transcode the audio to desired format. If transcoding to AC3, use 640kbps, the max bitrate for AC3. Also consider EAC3 , the successor to AC3…

My setup: LG B7 OLED ← HDMI-ARC → Denon AVR-X4300H I disabled DTS in the Plex app (my TV is old enough to support DTS), then played a movie with DTS-HD MA 5.1 audio and another with TrueHD + Atmos 7.1 audio. Plex Media Server transcodes DTS-HD MA 5.1 to AAC 5.1 at 774kbps. The TV or Plex app see…

DTS incompatibility?

No. For two reasons:

as stated above, newer TVs not only no longer decode DTS audio, but also don’t passthrough DTS anymore
The capabilities of a SPDIF or TOSlink connection are not sufficient for the newer and higher quality audio formats.
Forget about passing through DTS-HD MA or Atmos over such a connection in general.
