Hello,
Is audio Passthrough in Kodi Leia solved differently than in Krypton?
Because on my Philips TV PFT6550 (Android 5.1) passthrough works corectly in Kodi 17.6, but in Kodi 18 i have no sound, no output on receiver. Same Settings.
Some possible solutions?
Disable passthrough and let Kodi autput the audio as stereo? What benefit does one have to bitstream 5.1 channels to a TV with only 2 speakers?

He said he have a receiver
oh damn. My apologies. Missed that part.
Might be SHIELD -> TV -> Receiver
I now guess more that it's Kodi on Androd on Philips TV -> Receiver
Probably via ARC.
I have tested and here are my other findings. The difference is most significant on DTS sound. In Kodi 17.6 works passthrough correctly on movies with DTS sound, i have 5.1 output on every file with this sound, in Leia nothing, no output, neither 5.1 nor 2.0. That is why I ask for info about difference between Krypton and Leia in audio processing, i dont understand why it works on one, and not on another.
With standard 5.1 sound (AC3) is situation more difficult, some movies passthrough correctly in Krypton and Leia, both, some movies not.
I don't think you are right. Krypton removed passthrough via PCM hack. It only works via standard APIs. And MediaTek devices (Sony and Philips) do not implement ENCODING_DTS currently.
You should provide a
debug log of a playback attempt.
Sorry but i know i am right. In Krypton works passthrough for movies with DTS audio fine, maybe it is not true DTS, because is enabled Dolby Digital Transcoding, but for me is important, that output is surround, for 5 reproductors.
Now tested again, new clean instalation both, first Krypton, second Leia, same movie (Life of Pi), same settings, only allowed passthrough and enabled Dolby Digital Transcoding. Thats all.
In first case (Krypton) movie played correctly, with 5.1 output, in second (Leia) not.
Here is logfile from both:

Have you actually enabled debug mode on both attempts cause a lot is missing.
Regardless the v18 log is full or errors making it seem like a completely broken Android firmware issue (blame Philips).
Sorry, my fault, here again:

I understand that guilt is primarily on Philips side, their firmware for older TVs is peace of shit. But when passthrough of DTS works on Krypton, isnt possible make change in Leia code, some build for Philips TV, modified by working Krypton?
I have actually never seen an Android TV with MediaTek MT5593/MT5861. This really looks to be some very old unsupported HW (still on Lollipop).
As expected, DTS is not supported:

DTS should work when being transcoded to Dolby Digital which happens on your side:

Dunno why playback fails though. Works fine for me on Leia with the transcoding...

Device specific changes is something we will never do again cause it's just not worth it for us.
We succesfully open AC3 for your DTS after transcoding:

That way nothing will come out ...
to Martijn: OK, I understand.
to fritsch: And what does "big audio sync error" mean, is audio too big for sync? Because in the same movie another track in standard dolby digital (not DTS) work correctly, passthrough success, 5.1 output on receiver.
https://paste.kodi.tv/padiyewaso
9.13 - start movie with DTS audio, no passthrough
9.14 - change track to Dolby Digital track, passthrough ok
9.15 - change back to DTS, no passthrough
