jamvids 37 Posted April 21, 2016 Share Posted April 21, 2016 Has anyone got one of these and got any form of 5.1 through an optical cable. I have tried many combinations in the settings, both Emby and TV. Not having any luck. A little help? Sent from my E6853 using Tapatalk Link to comment Share on other sites More sharing options...
mini__me 23 Posted April 22, 2016 Share Posted April 22, 2016 (edited) I have one but with an Atmos amp attached on HDMI4 to enable the ARC and therefore not with an optical cable, however I it will still only bitstream DD and will not pass through DTS, so I have to check the box to convert DTS to DD. Still a massive improvement however for general household viewing, I plan to add a standalone device at somepoint (used to be a dedicate HTPC prior to moving house) directly connected to the amp to give me back Dolby TrueHD and DTS HDMA and maybe Atmos if the box will support that as well.

ebr 14905 Posted April 22, 2016 Share Posted April 22, 2016 The optical cable has limited format support. It may be that the TV is trying to send DD+ which that cable doesn't support. It also cannot support multi-channel (beyond stereo) LPCM. Link to comment Share on other sites More sharing options...
jamvids 37 Posted April 22, 2016 Author Share Posted April 22, 2016 Will have a look into that. My older sony tv does everything if I cast to it via dlna. The Android one also passes through the xbox one dts signal okay. Maybe a frustrating sony thing. I sometimes get 5.1 ac3 out of it but that's it.

Sent from my E6853 using Tapatalk I have two Sony KD-55X8500C in the household. What model do you have? The multi-channel pass-through has been a problem for a long time and there have been several improvements. I don't use any optical connections but I can't help thinking that DD should pass through ok, DTS won't due to Android TV limitations on the Sony (I believe). What settings have you looked at? And, if we ever get Android TV version 6, I believe that will pass through DTS as multi-channel but I don't know what will be the case with optical connections on that either. My inference is based on using Android TV version 6 on a Nexus player with an HDMI ARC connection so I don't actually know what the Sony device will do with DTS when (if) Android TV version 6 is released for it. I can't say that passing DTS as multi-channel is all that good either. My impression of this (purely from listening to the audio so it's subjective) is that the DTS sound field processing (or parameters or whatever) is not applied to the audio leading to less than optimal audio. It might be worth trying Kodi (with the Emby plugin) on your device. Kodi doesn't use the Android TV audio infrastructure (at least to some extent) and is able to pass-through DD and DTS. Sadly, Kodi v16 won't pass through DTS-HD MA (I'm not sure about the status Dolby TrueHD in Kodi, ....) unless Android TV is at version 6 (at least I believe that is the case) and we won't know what the Sony will actually do with this until we get it. So for us the situation is not all that good IMHO but not all that bad either. Ian Link to comment Share on other sites More sharing options...
jamvids 37 Posted April 27, 2016 Author Share Posted April 27, 2016 I think patience is the key here, I hope Sony will solve these problems, like I say my older and significantly cheaper model is really good with dlna as long as I cast to it. I use optical with that and most audio it will pass through, AAC 5.1 is still just stereo though. If it doesn't like a particular format I just switch to chromecast. The colours are richer if use dlna too. My android tv is model is KD49X8309C. 4K with hardly any 5.1. and not much happens over dlna either but not bothered about as I'm sure android tv will develop. The whole reason for this purchase is for emby. One plus side is flac sounds amazing, though I have 3 chromecast audio's around the house so I don't use it that much, oh and the upscaled picture is just beautiful. May give kodi a go if I get some time. I always have my xbox too. Cheers Sent from my E6853 using Tapatalk Link to comment Share on other sites More sharing options...
jamvids 37 Posted April 27, 2016 Author Share Posted April 27, 2016 In fact if the devs see this, can we have all AAC 5.1 Transcoded to ac3 for any client? Sent from my E6853 using Tapatalk Link to comment Share on other sites More sharing options...

It also cannot support multi-channel (beyond stereo) LPCM. There is another possibility. It turns out that there is a known problem with the current Sony Android TVs that relates to DD (in truth I don't know what models are affected, I just know mine (KD-55X8500C) is and I've seen other reports of the problem, most likely from people with different models). Sending DD with a bitrate greater than 448k does not work, anything lower does. Until I became aware of this I was very confused with why some things would play and others not and this might be relevant to Optical connections as well. It's worth investigating IMHO. 1 Link to comment Share on other sites More sharing options...

I have tested this and I see it isn't a problem with Emby. The 448k limitation problem was reported against Plex for Android and it was claimed to be a Sony problem. Attempting to play > 448k DD would cause the player to hang. Emby for Android doesn't have this problem for me. That could be due to the Sony being at 5.1.1 and so using VLC and not some other player, I don't know. This is just more information which might be useful for subsequent development.

MrWebsmith 598 Posted May 22, 2016 Share Posted May 22, 2016 thanks for reporting this... as you say.. the more info the better the devs can work "around" or eventually improve the situation Link to comment Share on other sites More sharing options...

I could be wrong but it looks like VLC is not longer used with Emby for Android TV (at least for the playback I use). Now, when direct playing videos that have DD I get stereo only coming through to my receiver. If I enable the bitstream option DD <= 448k gets passed through fine, anything higher causes playback to hang so it seems my my comments above have now become relevant. I didn't even try DTS but I expect the symptoms will be the same as what used to be seen with Plex, a hang of the player. Ian Link to comment Share on other sites More sharing options...
