When using the emby app installed on the TV and trying to play DTS trough passthrough via the HDMI the eARC connection between the receiver and the TV the receiver gets the PCM signal but for some reason emby software decode the audio instead of sending it trough 

Works fine when sending ACC trough PCM (ACC is supported by the TV but not DTS)

Is there a way to change emby to send the audio trough passthrough from within the app instead of only having the option to either do auto or downmixing? Or am I misunderstanding something? Strange thing is that in dashboard on server side (using iphone app) its showing English DTS-HD MA 7.1 (Default) >> Direct Play even though it shows something else in the TV app

Sent in debug logs from the app on the TV

Hi there, how are the audio options configured in the Emby app on the TV?

Hi Luke, the setting for audio in emby app on tv is set to auto

 

Below pictures of settings in app and TV and also examples of the same video running with 3 different audio tracks, True HD, DTS, ACC

 

Also sent in new logs from app on tv

Hi.  Your TV does not support passing through DTS, DTS-HD or True HD so we are decoding those locally.  Are you getting 5.1 PCM at the receiver?

The only tried and tested way of getting HD Audio to your receiver (which does support DTS-HD and True-HD) is to use an Nvidia Shield and plug it directly as one of the inputs on your receiver.  (ie bypass the need for ARC/eARC).  The downside is your receiver needs to be able to passthough 4K Video - and being an older receiver, I'm not sure it can.

I've not seen anybody successfully use the eARC on their TV to passthough HD Audio from any App - technically eARC it can do it as that's what it was designed for - but it may be a TV OS/Android/Hardware or App limitation, I'm not 100% sure.

If on auto and software decoding I only get 2 channel stereo through PCM according to receiver

Thanx for the information, the receiver only support HDMI 1.4a so I assume that the Nvidia Shield option is not going to help in my case.

HDMI version 1.4a with support for 3D video, Audio Return Channel, Deep Color, x.v.Color, auto lip-sync, and HDMI-CEC.

So the only option for HD-Audio is an nvidia Shield with a 4K HDMI 'splitter' - one HDMI to the TV and one to your Receiver.

Being honest with you, unless you are throwing in Atmos and/or DTS:X into the HD mix, and you have some speakers worthy of HD Audio, then it's probably not worth the effort over E-AC3 or even high bitrate AC3 imo.

Okay, then your options would be to select an AC3 (DD) track, accept a stereo decode or select the option to convert those other tracks to DD on the server and then you'll get DD 5.1 at your receiver.

Personally, I'd select the last option.

Hi, just so I understand, the last option is there a setting that I should change/check on server and or client side?

It is the "Audio Handling" option in the app.  Set it to convert to DD.
