DTS, Dolby 5.1 on Playbar, 2015 edition!

Hi all

I am writing this post in the hope it may help those struggling with the above issue(s). The first topic which appears on this in Google is the post at https://en.community.sonos.com/home-theater-228993/solving-the-51-dts-issues-with-the-playbar-34523, which is now out of date. For my part I wanted to set out what I did to "resolve" this issue (or more accurately, work around it).

Since the above post, Sonos have written a few useful notes. The most helpful is: https://sonos.custhelp.com/app/answers/detail/a_id/1945/~/maximizing-playbar-sound-from-your-television.

A further note deals with the XBOX work around (https://sonos.custhelp.com/app/answers/detail/a_id/2490/session/L2F2LzEvdGltZS8xNDQxMjA4NzE0L3NpZC9JdER6cXR2bQ%3D%3D) and another provides the details for PS4 (https://sonos.custhelp.com/app/answers/detail/a_id/3075/related/1).

The Issue

Playbar with 2 Play:1s and a Sub is a 5.1 Surround system. However, because the Playbar connects through a Digitial Out/Toslink/SPDIF, its limited bandwidth prevents it from EVER being compatible with DTS-HD, Dolby True-HD or any other lossless/HD audio. However, it is possible to play Dolby 5.1 providing your TV can output a Dolby Digital signal through the Digital Out.

People realise that they are only listening to Stereo when they go to About My Sonos System and realise that the AUDIO IN listed under PlayBar is STEREO. When its 5.1 it will say Dolby Digital 5.1, or when Dolby Digital 2.0, exactly that.

DTS

DTS will have to be re-coded as Dolby Digital to be played by the PlayBar, else it will be silent (displaying "Audio not supported"). There is no way of playing DTS itself.

Work arounds: My experience

I read the above post and went off to buy a switch (although, this one in the UK http://www.amazon.co.uk/gp/product/B00DZIXIMQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00, called Portta 4x1 HDMI Switcher with Toslink and Digital Coaxial Port 3D Splitter with Remote and AC Adapter/ 3D 1080P). When I connected my BD-Player to this by HDMI, with my STB and TV, and connected the switch to the Playbar, it started to play 5.1. Result. However, this is a poor solution as you have to manually switch between inputs, have another remote, cannot use a magic remote or the input management system on the TV etc.

I thought about buying an XBOX (which my research indicted is the better media system when compared to PS4) it (with PS4) decodes DTS to DD 5.1 "on the fly.

I also thought about buying the OPPO BDP-103 for a whopping £400 as suggested by the post.

However, there are literally a handful of BD Players which also re-code DTS to DD (please see SONOS's own post). I purchased the Samsung BD-H6500 for a very reasonable sum and can now play DTS easily on the Playbar (obviously, recoded to DD5.1).

I have set my system up as follows. My LG 55EC930V is connected to the Playbar. This TV outputs Dolby Digital (and I think, even Dolby Digital Plus) via Digital Out. I have then connected my Virgin Media STB to the TV via HDMI (STB set to output Dolby Digital Audio) and the BD Player via HDMI, which is set to output recoded DTS.

My issue was that my wired Home Cinema system (Panasonic SC-BTT270) would not output DD as it only had an Optical In, so I had to buy a new player. I highly recommend the one I bought, it plays great.

Also, my Playbar also plays 5.1 from Netflix, Amazon Prime video and Live TV (though, not Youtube for some reason).

Other work arounds

You can also work around the DTS issue by connecting the Playbar to an XBox or PS4, or at worst, a switch.

I hope this helps!!! 🙂

Hi chrisredmayne

Sorry that you are getting a bit frustrated trying to sort all this information out. Here's the down and dirty...

1. Playbar will only process DD 5.1 if your TV will pass it over Optical - some TV's will and some won't - check your manual or call the manufacturer tech support.
2. Using a HDMI switch will not cause you to lose TV audio as long as it's properly configured. As the name implies you will have to select (switch to) the correct source unit to view and listen to content.

That being said...
A. Are you trying to get audio from different sources to play through the Playbar? If you have enough HDMI inputs on your TV you don't need a switch...just the optical cable to run between your TV's optical out and the Playbar's optical in.
B. Are you having trouble setting up surround (DD 5.1). Assuming you've verified condition "1" above. Also, you'll need Play 1's x 2 or Play 3's x 2 for the rear surround speakers. The Sonos Sub while recommended is optional but you only get DD 5.0.

Please post back with additional questions. Everyone is here to help!

Cheers!

My tv wont passthrough the audio so I'm trying to get it to use audio from the tv, pc and ps4 without having loads more wires, switches and plugs everywhere. Ordered a three way optical switcher from amazon so I can get the ps4 and tv optical wires in, will hang on and see how that works! I might just live without PC audio for now as that seems more troublesome as I would need an hdmi to optical box I think ? Stressful times setting this up!

You say...."I'm trying to get it to use audio from the tv"...by it assume you mean the Playbar. Then you go on to say.... "so I can get the ps4 and tv optical wires in". Something doesn't add up???. I understand that some TV's won't pass DD 5.1 over optical; but yet you say you're trying to get..."the PS4 and TV optical wires in..."

Question...Does your TV have an optical out or not??

Hi Pico

"I also found a link for Italia: http://www.futurhome.net/octavafile/octava_hd41arc.pdf"

Here's the direct link to home page for the Octava dealer in Italy: http://www.futurhome.net/

Thank you for your help, I fixed everything with a new blu ray player ( Samsung 5900, for around 100 Euro).
Definitely the problem is the PS4 itself and his audio processing with blu ray film (but with games audio is ok lol).

Helpful tool for shoppers of a new 4k TV screen:

Here is a 2016 list of TVs that support 5.1 surround audio pass-through via optical cable connecting the TV to Sonos Playbar (Source ->TV ->Sonos Playbar), meaning that the TV can natively pass through the 5.1 audio (Dolby and/or DTS) to Playbar, through the Optical Cable, without downgrading to stereo. The source can be a PC, Blue Ray player, video game console, etc...

http://www.rtings.com/tv/tests/inputs/5-1-surround-audio-passthrough

A more recent and up to date list of 4K TVs with full reviews indicating 5.1 pass-through support can be found here:

http://www.rtings.com/tv/reviews/by-resolution/4k-ultra-hd-uhd/best

Click on review and scroll down to read about 5.1 pass-through support.

This should enable playing all 5.1 Dolby Digital audio sources on the playbar, with no downgrading to stereo, assuming you have the 5.1 surround hardware in place, with no need for any HDMI switch or Blue Ray player in between.

Sonos Playbar still won't play DTS audio in this case even when delivered at its doorstep due to lack of support, but thought I would save the trouble for those who are looking to buy a new 4k TV screen with native 5.1 Dolby pass-through support via optical cable.

Thoughts?

I just bought the samsung KS8000 as shown here (http://www.rtings.com/tv/reviews/by-resolution/4k-ultra-hd-uhd/best). I did my research and I know that my TV supports dolby pass through via optical cable which you can see in the screenshot (My Sonos Info), it says 'Dolby Digital 2.0. I was looking forward to connect my new tv with sonos but the sound quality i am getting is terrible.

My problem is with how LOW the damn sound is when playing content through HULU (smart app in tv). It just doesn't sound like "surround". (I have playbar and 2 play 1's configured as surround. Optical cable is connected from PLAYBAR to samsung 'One connect'.). I need some advice here because this is driving me bonkers !!! I have to turn my sonos volume to 50% or more just to listen dialog and it all seems coming from playbar. When i play radio / itunes music on my sonos via iphone app it sounds amazing. Then why is my TV sound is so crappy even though it is 'Dolby Digital 2.0' and what can i do to fix this ??
Any ideas help would be appreciated ...

Well, I'm pretty sure that Dolby Digital 2.0 is just a stereo signal. That's the reason you're not getting surround.
As far as the lack of volume in the Hulu app, well I don't know what to say about that. I don't use Hulu myself. How do the other apps in your TV work in regards to the volume? If they play louder than that indicates just an issue with Hulu. Maybe you can contact your TV's support team and report this issue?

@tom thanks for your response.

It makes sense why there is no surround sound because like you said dolby digital 2.0 is stereo.
I was playing content though Hulu (built in app). I did some research and seems like Netflix has 5.1 dolby digital audio on some movies and tv shows. Does that mean if i play content through netflix I should see 'Dolby Digital 5.1' on my SONOS app as an output ??

It's possible. Assuming you would be playing through the Netflix app on the Samsung TV, then the app needs to support DD 5.1. If it doesn't you just get stereo.
