Hi all. Is it true or has anyone heard that DTS will be coming soon by the end of the year ?

That worked. I changed some of the tv audio output settings. I now got this showing on my app. I guess that's fixed it? Thank you.

Yes, it is true. But from what I can tell, it only appears to be lossy DTS Digital Surround support, not support for lossless DTS-HD Master Audio or DTS:X.
“Sonos also plan to add support for decoding DTS Digital Surround later this year via the S2 platform on Playbar, Playbase, Amp, both generations of Beam, and Arc.”

Now you'll have to explain how a DTS-MA or DTS-X track from a blu-ray will play on a Sonos soundbar. Is it absolutely necessary for the TV to have a "Passthrougth" feature that supports DTS? Will the signal be "degraded" to simple DTS or can it be converted to Dolby Digital-True HD/Dolby Atmos? I would like to note that simple DTS 5.1 will be a huge step forward, especially regarding dynamics and surrounds, instead of stereo. Therefore, thank you, I'm looking forward to the details and future announcements.
A DTS-HD Master Audio and DTS:X track has a core lossy DTS Digital Surround track. This is similar to Dolby TrueHD having a core Dolby Digital track. DTS Digital Surround is what Sonos will begin to support. From what I can tell, DTS Digital Surround has a slightly higher bitrate than Dolby Digital, so the audio should sound a little better than standard Dolby Digital.
- If your TV and soundbar have HDMI ARC (like the Beam Gen 1) and your TV has DTS passthrough, when you play a DTS-HD Master Audio or DTS:X disc, you will get DTS Digital Surround audio (after the DTS update).
- If your TV and soundbar have HDMI ARC and your TV has Dolby Digital passthrough, when you play a Dolby TrueHD or Dolby Atmos disc, you will get Dolby Digital audio.
- If your TV and soundbar have HDMI eARC (like the Arc or Beam Gen 2) and your TV has DTS passthrough, when you play a DTS-HD Master Audio or DTS:X disc, you can get DTS Digital Surround audio (after the DTS update) OR multichannel PCM (depending on your player’s settings).
- If your TV and soundbar have HDMI eARC and your TV has Dolby Digital/TrueHD passthrough, when you play a Dolby TrueHD or Dolby Atmos disc, you will get Dolby TrueHD or Dolby Atmos audio.
I’m hoping this DTS update will be just the first step to Sonos eventually supporting DTS-HD Master Audio and DTS:X over eARC for the Arc and Beam (Gen 2).

I would like to thank the Sonos team for finally taking into account the request of many customers regarding DTS. This was a huge drawback considering the high price of Sonos products.
As a Sonos Beam+Sub owner, I had invested in a Sony UBP-X800M2 player connected to a Sony TV of the same generation (the only combo allowing DTS->LPCM->Dolby transcoding, a miracle I still don't understand). But I know other people who are not so lucky and are stuck in PCM stereo when playing DVD/Blu-ray with a PS5 and the Beam.

It is. A lot of TVs simply won’t do it, and that’s probably one of the many reasons why Sonos has been slow to implement the feature - it’s not going to reach everybody. Samsung and LG are big offenders here - they’re probably not willing to pay for the licencing. Recent Sony and Hisense TVs are probably ok. rtings maintain an up to date listing of TVs and passthrough support. I’m not sure if I’m allowed to link it here?
As always a way around it is to use a player that can reencode DTS to Dolby or LPCM on the fly.

Pretty excited about this update, any idea when it'll happen (outside of the vague "later this year"?)
There is an Audio Advice video that mentions a November 21 update. Start at the 4:06 mark:

Sonos is still working on the 7.1 to 5.1 downmixing issue. But I have noticed an improvement with DTS discs on my UB820 player. I have the Arc/Sub/Play:1s setup. Using a 7.1 DTS Sound Check on a DTS Demo Blu-ray disc, the two rear surround channels used to not play any test tones out of my Play:1s. Only the two side surround channels would play audio. Now all four surround channels play audio out of my two surround speakers. The Sonos app still displays the audio as 7.1, but it sounds like the 7.1 mix is being properly downmixed to 5.1.
My app is showing DTS Surround sound 5.1 now after the update. I have Panasonic VT60 hooked to Nvidia shield and I am playing my stream through Kodi which is setup as Passthrough.
I also saw this and was surprised at how under the radar this news is!
As a long suffering Sonos user who loves using Disk Format, i’ve had to jump through hoops to get DTS to play on my setup, and after years of Sonos telling me that this nuisance wasn’t their concern, they’re finally bringing DTS support to their home theatre products!!!
It might be a little downplayed because they’ve now allowed all eArc devices to process Multichannel LPCM devices so we’re covered for full surround for more DTS disks (though I’m not sure about DTS:X), but this doesn’t solve anything for the Playbar -- which is part of the DTS update.
It’s still a head scratcher that none of the higher end DTS formats are being supported though - guessing technical issues and too much development cost plays a part. Lets be honest -- disk using purists who crave the highest level of audio quality are a quickly shrinking minority.
DTS working okay here too.. 👍
 Blu-Ray Player to Sonos Arc LG C9 TV set to ‘pass-through’ |
Have just discovered this thread whilst trying to test DTS through my setup. I have the (dreaded) UB820 player and a Panasonic HX940 series TV. My Sonos setup in the room is a Playbar and Sub.
After much huffing and puffing and panicking about the performance of the Blu-ray player (after reading this thread!), I eventually deduced that the TV was my weak link. It would happily passthrough Dolby 5.1 (audio out from player via HDMI and then from TV to Playbar via optical) but DTS was showing as PCM Stereo in the Sonos app.
Did some digging around and found that the TV doesn’t support DTS. So I tested running the optical cable direct from the UB820 to the Playbar and it worked flawlessly.
Now I just need to order a second optical cable and remember to switch them over in the back of the Playbar when playing physical media. As much as I might like to use this as an excuse for a new TV, I don’t think it will fly...
Hello, I’m excited to get DTS working on some of my movies, but for some reason not all of them work. DTS-MA 5.1 movies ouput DTS 5.1 Surround with no issues. However, when I play DTS-MA 7.1 movies, I get Dolby Digital 2.1. Any ideas why? I assumed both DTS-MA 5.1 and DTS-MA 7.1 would downgrade to DTS 5.1 Surround. Thanks in advanced.
Here’s my setup
TV: Sony X900H, passthrough enabled in audio settings
Soundbar: Sonos Arc plugged in eARC input
Source: MakeMKV Bluray rips running on my NAS
Software: Plex in native TV software, had to change output to optical to get any 5.1 audio
Does anyone know (or have this same problem) why I can only get DTS if I turn off ‘eARC’ on the LG B9?
Surely this is a bug? Seems a bit weird that DTS comes up as unsupported audio when eARC is on, but appears all fine (and in 5.1) when it’s off.
It’s not the end of the world (much prefer this to no DTS support at all), but it’s a bit annoying having to keep switching it on/off every time I play DTS content.
This link may help explain it for you…

Hi, yes your C8 does passthrough and yes it supports DTS as a codec. You can enable the passthrough option in the audio menu on the TV. DTS is basically like Dolby Digital 5.1 for reference and the one Sonos will be supporting. DTS:HD is like the equivalent of 7.1 and DTS:X is like equivalent of Dolby Atmos although both those two won't be supported, but should get mixed down to standard DTS or multichannel PCM.
I’m not sure whether I misread that post you linked to, but my TV is the B9 so supports DTS passthrough and eARC.
So it should be playing DTS without me needing to turn eARC off.
Maybe it’s an issue with the TV firmware then? I have the LG C9 TV, firmware version 05.10.25 and DTS 5.1 works whether I set HDMI-2 to Arc or eARC. (I have my Digital Sound Out set to pass-through and the DTS codec is set on the Blu-ray player in my case).
I am sure Ken can answer for himself when he comes back on, but I don’t think he is suggesting a direct connection from BRP to Arc, just that he can now get DTS audio from his BRP playing on the Arc by passing it through the TV
I had a slight hope he had figured something out to bypass the TV without the complications of something like the HDFury, which might solve the Panasonic UB820 DTS to ARC issue blocked by my TV.
As an update to my post further up, I have the UB820 and am now getting DTS 5.1 for my DTS Blu Rays.
The only downside is it required me to toggle eARC off for the Arc, but it’s easy to toggle it on/off, and actually having it off still gave me Atmos and the like.
I can talk through my settings if helpful?

Interesting! Please explain. My LG CX still doesn't support DTS, but I’ll give it a try anyway.
Player settings (UB820):
DTS/DTS-HD - Bitstream
BD-Video Secondary Audio - Automatic
LG B9 settings:
Digital Sound Out - Passthrough
eARC - Off
Mine is a B9 but someone with a C9 has said this worked for them too. It may not work for CXs but worth giving a shot.
B9 and C9 can pass DTS as have the codecs. C1, CX new ones etc had codecs removed.

Thank you. Sadly for me, not the solution through my LG CX TV and my Panasonic UB820. But was worth a try as I was hoping maybe it would at least allow LCPM to pass through from the Panasonic UB820.
Happy for you! I know how meaningful the sound experience when you can play a DTS only Blu-ray without miserable PCM Stereo on the Sonos Arc. When I switched to using the Sony Blu-ray player for DTS only blu-rays and heard Multichannel PCM Surround Sound for the first It was a jump for joy!
It’s taken too long for Sonos to bring DTS to the playbar and beam. But I’m so pleased to have it even in its basic format.
I can now play 4K ultra Blu-Ray with 5.1 surround sound. James Bond Skyfall just sounds amazing.
I’m using:
sound: playbar, Symfonisk surrounds and sub.
tv: LG OLED55C7
blu-ray player: Panasonic UB154EB

Sadly my new LG CX TV does not support any form of DTS 🤬
Hmm, so I’ve updated but it’s not working for me. I’m using an LG B9, which I understand has DTS
support. But when I play DTS discs, I’m getting ‘Unsupported TV audio’ on the app and no sound.
