Edision: MKV DTS 5.1 not working. DTS-HD OK

#1

Beitrag von dfdsffsuio »

Hello, am using OpenATV 7.2 on Edision OSMega.

MKVs with DTS-HD or DTS-X audio stream play/passthrough audio without issue from the Edision. The DTS indicator lights up on the soundbar and sounds great. Any MKV with DTS-HD all work fine.
MKVs with DTS 5.1 do not passthrough audio. There is no audio at all and DTS indicator remains off on soundbar. Video is fine. Tried both hdmi and optical connection from edision to soundbar.
All MKV files (DTS 5.1 or DTS-HD) playback fine on same soundbar but connected to a windows 10 pc digital out and media player classic.

Anything I can try ?

Using MediaInfo and the sample.mkv here with the 5.1 dts:


Format : DTS
Format/Info : Digital Theater Systems
Codec ID : A_DTS
Duration : 6 s 763 ms
Bit rate mode : Constant
Bit rate : 1 510 kb/s

Frame rate : 93.750 FPS (512 SPF)

Delay relative to video : 4 ms
Stream size : 1.22 MiB (15%)
Title : DTS 5.1 @ 1509 kb/s

info from a file (dts-listen-long-lossless-(www.demolandia.net).mkv) that plays:



Format : DTS XLL
Format/Info : Digital Theater Systems
Commercial name : DTS-HD Master Audio
Codec ID : A_DTS
Duration : 27 s 30 ms

Frame rate : 93.750 FPS (512 SPF)

What Edision are you talking about?
And what is the destination soundbar?
Connected directly to the box, or via HDMI-ARC over teh TV (which one is implemented)?

The Sound bar is connected directly to the box.

I know box and sound bar are set up/connected correctly as mkv's with DTS-HD or DTS-X play back perfectly.
I know the DTS 5.1 test files are good and the sound bar can handle them as the DTS 5.1 mkv's play back perfectly in Windows 10 and the same sound bar can decode them without issue.

Just for reference, I was able to fix this by re-encoding the audio bitrate of my movie files.
For DTS 5.1 encoded files, the bitrate must be a minimum value of 768 kb/s.
No issue with playback and audio pass thru after that.
Something like HD Video Converter Factory Pro for example is super easy to use for this task and will do the job in a couple of minutes. Recommended
