Hi I'm wondering if someone can help me understand how this DTS support will work. I'm really new when it comes to all this audio talk and I don't really understand it. Sorry if this is a dumb question. 

I have an LG C8 TV which is connected via arc to the sonos beam and I have 2 one SL speakers for surround sound. 

I watch a lot of movies and I download the movies then copy them to an external HDD that I then connect to my TV. 

Before I download a movie I always had to make sure it had DD5.1 because I knew my beam supported that codec but with this DTS update will I be able to download DTS hd master audio films and have my TV convert the audio to a DTS codec that my beam will support or will the TV not do that ? 

I'm just really confused as to what DTS codec the beam is going to support and what the passthrough thing means on the TV. I don't even know if my TV even does a passthrough. 

I got to say I’ve given up on getting dts to work on my Xbox series x, Reading through these forums I’m amazed what hoops people needed to do to get Dts work, so I’m going to pull out my old blu ray player connect to my switch and hope for the best.

I particularly like this line:

But ultimately, use your ears to determine what sounds the best to you.

You probably can get an optical switch as a good compromise. 

I want to try the optical cable too with the UB820 to Sonos Arc to bypass my TV for direct DTS from the UB820 to the ARC.

What settings did you change in the UB820 to split audio to optical ? Also does your TV support eARC?

P.S. If you do spring for a new TV ( good time of year to do it with all these sales), my own lessons learned--make sure it supports all forms of DTS and DD. The newer Sony TVs seems to support both from the little I've investigated since I stumbled upon this DTS-less brouhaha after I made all my purchases. 

On a related note (and feel free to ignore if it takes the thread off topic), does anyone have latest word on the Sonos fix/improvements to handling LPCM 7.1? (it’s related to the above b/c today several players can output DTS as multichannel PCM - but sometimes it’s LPCM 7.1 even when the source is 5.1!).

That doesn't work either. It still says Stereo PCM. If I change DTS setting to PCM it then says on the Sonos app Dolby Digital 5.1

Just a few settings to change should get you there. This is how I have it set up.

1. Everything going through eARC on the CX TV
2. Make sure your Sonos, TV and Player have the latest firmware
3. Set the CX TV Sound/Additional Settings/Digital Sound Out to “Passthrough”
4. The Sony player Audio Settings/Digital Audio Output can be set to  “Auto” 

• Initially I set the Sony player Digital Audio Output to PCM but since some firmware updates seems “Auto” brings multichannel PCM 7.1 too.
• If I leave the CX TV set to passthrough I can also hear Dolby Atmos Blu-rays from the Panasonic player which I have in HDMI 3 and multichannel PCM 7.1 from DTS Blu-rays through the Sony player in HDMI port 4

Thank you so much! I'm getting multichannel PCM 7.1 with those settings (kept it on auto on the x700 for now). You made my weekend! The bizarre thing is that I definitely tried those settings before, made sure the new blu ray player had updated software, and made sure the Sonos system was updated. Since I have my tv set to auto update, I didn't check it. After your message, I looked in my tv settings and auto update was still on. However, there was a note that said the tv had been updated and the install would occur with the next restart. Restarted the tv and install complete. So either this update occurred at an extremely coincidental time, or there is an issue with the auto update that required me to trigger it by opening the setting. Nevertheless, I'm super relieved not to see the dreaded "Stereo PCM" on my Sonos app. 

Woot Woot 🤩

Multichannel PCM 7.1 is like a breath of fresh air when that sound stage suddenly opens up across your room after suffering from PCM stereo. I know that feeling well. Enjoy!  

Hey folks,

Can anyone help?

I have Sonos Beam Gen 1, Sony Bravia XR55 A80J, I have a passthrough setting, which I can enable in the Google TV sound settings menu, but..…I've tried to watch content from Sony's Bravia Core HD streaming service, the audio is not coming through.

The formats are DTS, IMAX DTS etc, but so far have not been able to make it work.

Not an issue for the vast majority of what we watch, and the content on the Bravia Core service usually has another non-dts audio stream, and, if I disable the passthrough, the TV will decode to stereo.

Just seems that either I'm doing something wrong, I've misunderstood, or the update hasn't worked.

Can anyone offer any advice?

Thanks

Is the Beam running on S1 or S2? If you you toggle eARC on or off, does it make any difference?

In the TV settings, be sure to set Digital Audio Out to Auto 1 and Passthrough to Auto.

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.

@GuitarSuperstarThanks for your description above! For players able to output DTS:X as multichannel PCM (e.g., some UHD players), do you think the better sound quality is going to be via multichannel PCM, or the (lossy) DTS Digital Surround? I guess maybe it depends on the quality of the player’s mixing to LPCM (in particular I have the Sony X800M2 so I’m most curious about that one, but also considering a UB820 in another setup)? Of course, once the feature is available from Sonos I guess I could try it both ways - but am curious in the meantime

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.

Pretty excited about this update, any idea when it'll happen (outside of the vague "later this year"?)

It's great news it's better than nothing, considering that Bose announced their atmos soundbar with no DTS at all...

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. 

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.

I am able to play back Dolby DTS-HD and I am hearing all channels correctly, the Sonos App shows the source as Multichannel PCM 5.1.

I tried swapping settings on the TV from passthrough to auto to pcm, only passthrough works properly.

I have an LG OLED C9.

For the audio source I am using a bluray disc.”

Thanks - yeah, still no luck, mine’s set to pass through.

I have a horrible feeling this is down to the blu ray player I have, the dreaded Panasonic UB820.

Does anyone have this setup and can confirm DTS is finally working?

Oh No!  Yes that is the problem. As I commented above, I have the same Panasonic UB820 and it doesn’t play well with Sonos for my DTS only blu-rays. I had to buy a second player just to play DTS only blu-rays in multichannel PCM on the Sonos Arc.

Drat. Was really hoping this update would get around that somehow.

So is my only option either a new player or an HDFury?

Unfortunately, from what I have spent far too much time out of my life googling and experimenting, options are limited to another player or something like the HDFury. The Sony player I bought cost a little less than the HDFury and I could have returned it for free if it didn't work out. Others use the Sony PlayStation too. 

Huge PITA that I wish I would have known about before buying all these components.
