No Surround Sound via DTS

I have a Sony 4K tv connected to a Sony Home Cinema System.

DTS files playback in stereo and not surround.

Help!

Just to add, I'm using the TV's built-in media player app.

Came here with the same issue.

Can't remember how it was with the EX500 model, but current one w817b sends via optical audio out only 2.0 if source track is dts.

Any chance to have multichannel dts track be transcoded into multichannel ac3 on the fly or this is just impossible by some technical limitations?

Dolby true HD comes as Dolby 5.1 with no problems.

Some .m2ts files I have with dts tracks have no sound at all. Though some of them not seen at all or unplayable by some reasons...


Thanks in advance!


Update.

Seems like I just have to add colored line in the section below?

<Video targetContainer="mpegts" targetACodec="ac3" forceInheritance="true">
<Matches container="*" vCodec="h264" aCodec="truehd" />
<Matches container="*" vCodec="h264" aCodec="flac" />
<Matches container="*" aCodec="dca" />

Are you feeding the audio out of the TV via ARC (Audio Return Channel via the HDMI cable) or the optical out?

To my understanding, most TVs will only output DD or stereo via the optical out. Few TVs will passthrough DTS. My brand spanking new Samsung 4K set (2 days old, less than a week on the market) has a menu option that says I can output bitstream. That is only using ARC I imagine (which is what I use). While I have a number of movies with DolbyTrueHD and DTS Master Audio, my AV receiver only indicates it is receiving DD or standard DTS via the built-in DLNA player. But, it does play them with no difficulty. Since my set is so new, I expect firmware updates to appear rapidly. I got one today, but haven't found out what changed yet.

Alexb, that line will probably be necessary, but that should be all it takes. Remember to restart the Serviio process (or the computer) after editing your profiles file.

I have my TV connected to a soundbar via optical out, and this output handles DD 5.1 or PCM 2.0, no DTS, ofcourse.

I've tried to add that colored line and have a very strange result. Made a short test and here's what i've got (all files are .mkv with h264 video codec, if this matters):

Skyfall (5 audio tracks) = dts 3f2r/lfe, ac3 5.1, dts 5.1, ac3 5.1, ac3 2.0 - only 1st track left, encoded into surround DD, can't change the track

Avatar (2 audio tracks) = dts 768kbps, dts 1536kbps - only 1st track left, encoded into surround DD, can't change the track

Real Steel (3 audio tracks)= ac3 5.1, ac3, dts - no changes at all, have all tracks available with dts as 2.0 pcm

*.m2ts file with dts tracks - no changes at all. still no sound. this is another subject, but anyways, i have list of 12-15 m2ts file and only 6 or so seen in TV menu, though here
http://pdf.crse.com/manuals/14HM094111/ ... st.html#10

i can see that TV should handle *.m2ts natively, at least video part....

PS. Still waiting Sony to add DLNA support for PlayStation 4... at least it can output both DD and DTS via optical to my SB.

OK. First, if the audio requires transcoding, you only get the first audio track and any additional tracks are discarded.

Now, for the M2TS file with no sound: I'd like to see the media info on that. Do you know how to do that, either with the MediaInfo program or with the FFMPEG command line?

For the M2TS files that don't appear at all: also need the media info for one. Remember that M2TS is only a container, and the video and/or audio codec used can vary. I know you say they are all H.264, but there are different levels of it, and if for some reason they are above Level 4.1, your TV may not support it. That would mean that Serviio won't display it, either.

i got the idea of dts transcode now. If 1st track = dts, then it'll be transcoded and any other tracks discarded. if 1st track NOT dts - nothing happens at all. seems clear now.

as for m2ts file, i will start a new topic and post media info of the files there.

Thanks for your help
