Sorry Da Flex that makes no sense. First of all it would setup audio output to Stereo. But even if I chose 5.1, if I deactivate passthrough, audio is send as PCM and the Receiver doesn't recognize the format anymore -> shows Multi Channel In.

And also the RPi is not the audio source, the source is the audio stream itself and the question is whether Kodi should decode it and send it as PCM to the receiver or should it be passed to the AVR as it is and let the receiver do the job of decoding. Later is the option I want of course.

I would like to know how LE handles the different audio formats. First of all here are my settings :

LibreELEC (official): 9.0.2 (RPi2.arm)
KODI-TV:~ # cat /storage/.kodi/userdata/guisettings.xml | grep passthrough     
<setting id="audiooutput.ac3passthrough" default="true">true</setting>     
<setting id="audiooutput.dtshdpassthrough" default="true">false</setting>     
<setting id="audiooutput.dtspassthrough">true</setting>     
<setting id="audiooutput.eac3passthrough" default="true">false</setting>     
<setting id="audiooutput.passthrough">true</setting>     
<setting id="audiooutput.passthroughdevice">PI:HDMI</setting>     
<setting id="audiooutput.truehdpassthrough" default="true">false</setting>

AVR is a Denon X4000, capable of all formats known nowadays. 5.1 Setup.

Above EAC3 aka DD+ passthrough is set to false because it won't play. Without passthrough it is passed as PCM (AVR shows Multi Channel In), same for Dolby TrueHD. DTS HD Master shows up as DTS Sourround.

Is this all as expected and normal for audio playback on Rasberry?

As you can read from the settings truehdpassthrough and dtshdpassthrough are set to false and it does not appear in the Settings tab, so there is probably a reason for that too. Probably RasPi is not able to handle that high bitrates? But then why is DTS HD MA recognized as DTS Sourround by the AVR and not as Multi Channel In (PCM) like the Dolby Formats?

No additional audio hardware. Model is Raspi 3 B+

Hi trent and Da Flex, you have to remember that I have the exact klone of Kodi running under Windows and there it works fine.

Have tried the default skin anyway, same result.

I also have tried to switch HDMI cables and conectors at the AVR, all without success.

It is somewhere in the LE / RasPi. But officials here a not keen on investigate that.

Around 10 diffrent DD+ samples I tested from my library play well on RPi2 and RPi4 from 5.1 up to DD+ 7.1 with Atmos, where my Denon AVR says Dolby Atmos. Tested with 9.2 latest git version.

That is really great.

Hi guys i am at the lates aplpha on my Raspberry Pi 4 4GB but i notice some screen Tearing when i am in the settings or so. is a known probleme and maybe a fix for it?

wrong bus

Quote from trent

I suggest update to LE 9.0.2

I am on 9.0.2, only the log was made on an earlier version.

Here's a log, if anybody is interested

I use also Netflix. Most of their stuff is also DD+. Doesn't work.

Files are not the issue. They play fine under Windows. Setup is the same.

All the same for me. Except I have 5.1 channels.

Chain is Kodi LE Raspi 3 - Denon X4000 - Sony TV

Same setup for a Windows PC gives DD+ output. In LE silence with 'Dolby Digital Plus capable' enabled, and Multi Channel PCM with disabled.

I will post my settings and signal chain tomorrow. You can compare and then maybe we work from there to determine the problem.

Danke

Quote from trent

It works for me. Pi3 running into Yamaha receiver. DD+ passthrough works

So if this is not a general issue LE has with the Raspi 3, how can I try to resolve the problem. Because I have no issues whatsoever passing any audio to my AVR. Only DD+ and only on LE Raspi. Kodi on Windows works fine.

I have checked all the Settings I think, so what can I do?

Quote from noggin

Kodi supports DD+ passthrough, so LibreElec support will depend on the hardware support in the surrounding Linux ecosystem that LibreElec uses, which means it's based on the hardware platform you are running.

noggin any insight?

Oh I didn't mention that, right.

I am using a Raspberry Pi 3.

I'd just like to know. Is it possible to get a definite answer to this question? Or is it a secret? So far I don't get it running with my AVR. But maybe I'm doing something wrong.

It works with Windows though.

Light please.

Yes, that would be nice. A first step would be a post or a statement here in the forum...

Well that's why I would welcome a statement from the developers.

Because I would like to know the facts rather than talk about the edge, chances and limitations.

Don't think it has anything to do with Netflix.

This is also true for local video files including dd+ audio tracks. And I also don't think the Raspi couldn't decode it. It is not that different from a bluray with dts hd master 7.1 which the raspi decodes just fine.
