EduardoSantos 40 Posted December 4, 2020 Share Posted December 4, 2020 Any movie with DTS audio stream gets transcoded though it used to play and passthrough to soundbar. Already checked TV/Emby configs. Was there any changes on this? Link to comment Share on other sites More sharing options...
ptre 2 Posted December 4, 2020 Share Posted December 4, 2020 (edited) Certain Sony TVs have issues with DTS HD MA Passthrough. For example: https://github.com/CiNcH83/bravia_atv2/issues/57 It does not affect all DTS signals so maybe when it worked, you played something else than DTS HD MA.

EduardoSantos 40 Posted December 4, 2020 Author Share Posted December 4, 2020 (edited) Thanks for your response! The issue relates to pure DTS audio streams. That's not DTS HD or MA. And it used to play nice some weeks ago. Edited December 4, 2020 by EduardoSantos Link to comment Share on other sites More sharing options...

ebr 14930 Posted December 5, 2020 Share Posted December 5, 2020 Hi. Your TV does not report support for DTS so it is being converted to a format it does support (Dolby). It is not transcoding. Just remuxing and converting audio. Link to comment Share on other sites More sharing options...
Solution Siutsch 9 Posted December 5, 2020 Solution Share Posted December 5, 2020 (edited) Same problem here. I made a FW Update for my Sony XF90 TV to Android 9. I think it can be the reason. But I haven't found any settings to change that within the Sony Android GUI. Edit: It is a problem with new FW 6.7140:https://community.sony.at/t5/android-tv/erfahrungen-mit-pie-atv2-fw-6-7140/m-p/3727479 Unfortunately the DTS formats were removed from the HDMI-ARC device info (see AudioDeviceInfo.getEncodings) in the Pie firmware. Apps that rely on this info (e.g. Plex) therefore don't do a pass-through for DTS anymore. Apps that use the Trial&Error principle (e.g. Kodi) can still output DTS formats via Passthrough. The pre-installed Media Player is also capable of this. Even DTS-HD is among the supported formats. This works by extracting and outputting the DTS-compatible core, but unfortunately this does not work without errors. With DTS-HD MA 24-bit, there are constant dropouts up to the complete stop of the audio output. Perhaps Emby can use the Trial&Error principle too, that Kodi uses? Or you can make the settings manually if necessary? Thanks. Edited December 5, 2020 by Siutsch Link to comment Share on other sites More sharing options...
ebr 14930 Posted December 5, 2020 Share Posted December 5, 2020 It is a bug in the firmware that will be corrected by the manufacturer. Putting in "force" options just lead to people turning them on and then spending time troubleshooting why their audio doesn't work. Link to comment Share on other sites More sharing options...
Siutsch 9 Posted December 5, 2020 Share Posted December 5, 2020 I don't think that Sony will "correct" that. Maybe you can provide a manually configurable file where you can do something like that? Link to comment Share on other sites More sharing options...
arrbee99 1561 Posted December 5, 2020 Share Posted December 5, 2020 Excuse the ignorant question, but I guess if I've got Shield > Soundbar > X90f (whether updated or not), I'm not affected by this ? Link to comment Share on other sites More sharing options...

arrbee99 1561 Posted December 5, 2020 Share Posted December 5, 2020 Thanks. Also, more generally, would anyone know - presumably it is a bug which can hopefully be fixed as opposed to some kind of deliberate removal which would presumably stay ?

That article links to a supposed "bug" report but I don't know if that is official. It is possible that it was removed deliberately for licensing reasons, I guess. Does the TV have an official "DTS" logo on the box? Link to comment Share on other sites More sharing options...
arrbee99 1561 Posted December 5, 2020 Share Posted December 5, 2020 Haven't dug out the box yet, but found this on https://www.rtings.com/tv/reviews/sony/x900f Link to comment Share on other sites More sharing options...
EduardoSantos 40 Posted December 7, 2020 Author Share Posted December 7, 2020 (edited) I understand a firmware can be a real showstopper. But it seems to me passthrough wouldn't require a DTS logo. What if other apps (eg. stock media player), using the same firmware, could play files passing throught DTS? Just tested this and it works fine: hooked a pen drive containing the same mkv provided when Luke asked for more details. The stock media player just played the file and tv passedthrough DTS audio to the soundbar. Edited December 7, 2020 by EduardoSantos 1 Link to comment Share on other sites More sharing options...

HanzoX7 8 Posted December 10, 2020 Share Posted December 10, 2020 My XBR-55805E is in the same boat. Started noticing the DTS tracks would not passthrough to my STR-DH790 amp perhaps a few weeks ago. Can't say if after the recent firmware update for sure, but most likely the culprit. The transcoding worked transparently to my ears, at least. I'd be willing to test the beta app, if someone can send it over... Link to comment Share on other sites More sharing options...

HanzoX7 8 Posted December 27, 2020 Share Posted December 27, 2020 (edited) I just got around testing the APK on my TV and no luck. On movies with DTS tracks stats for nerds says DTS (software decode) and my amp says PCM. Same movie in Kodi, my amp says DTS... Not sure if version 1.8.62 includes the fix from 1.8.61. Although, it says "Properly software decode DTS when not passing through nor converting", so I guess it's doing the right thing, just not what I would expect.

This is why we have the convert option - so you can get at least 5.1 out of these items by converting them to DD. Link to comment Share on other sites More sharing options...
