4K/UHD bluray players that decode DTS to Dolby?

With 4K bluray players starting to emerge now, seems we really need to start keeping straight which ones will allow those of us with Sonos Playbars enjoy some semblance of Dolby sound when certain 4K blurays only offer DTS. (Note, I haven't yet purchased a 4K bluray, so am unaware of the typical sound offerings.)

But we went through this once already, for regular bluray players, with many threads devoted to outlining the multiple Samsung models of bluray that decode DTS to Dolby 5.1 (I ended up buying a Sony that also does so). Now let's do the same for 4K players.

So far we have the Samsung UBD K8500 (which seems to clearly decode DTS to dolby.) Now what about the Philips? The Panasonic? The Xbox One S?

Anyone have any idea?

Quickly off topic - Brothers in Arms and So = two of my favorite albums of all time.

Back to topic. I noticed this morning that the LG site has the UP970 product manual available for download. I did so, and went to the audio section. There is a an option under "Digital Output" that is called:

"[DTS Re-Encode]" which had me excited for a moment. But as I think about it, I'm not sure that's what we want. The description is:

"Select if you connect this unit’s HDMI OUT or DIGITAL AUDIO OUT jack to a device with DTS decoder."

That doesn't sound like what we want. Granted the "Re-Encode" part of the setting is a great. My current Sony (non UHD) bluray has this feature....but it's called "Dolby" Re-Encode.

Ironically, seems like THIS player will transcode Dolby to DTS?? Obviously the opposite of what we want. There's also another note connected to this setting in the manual that says:

"If the [Digital Output] option is set to [DTS Re-Encode], the DTS Re-Encode audio is outputted for BD-ROM discs with secondary audio and the original audio is output for the other discs (like [Auto])"

Not altogether clear what that means. Sanity check here guys - anyone hazard a theory?

Carson - thanks for the update. Yeah, looks like the LG isn't going to transcode to DD5.1 :@

I'm guessing that when they state that it'll "Re-Encode audio outputted for BD-Rom discs with secondary audio and the original audio" is for the owner to hear the secondary audio track on a separate device connected via the optical port. I've noticed recently that Blu-ray discs are now coming with alternate language tracks in another codec. While I haven't seen DTS used for this I've seen many that had Spanish or French on the DD5.1 track. Yup, that's what the DD5.1 codec is now relegated to.

Since my TV supports both HDR10 & DV, I really wanted a player that was going to support both. But looks like Sonos isn't going to permit that.

I have to make a decision soon, as Planet Earth 2 comes out on disc soon and I've been really looking forward to seeing that in 4K. Well, I guess maybe I'll try the Samsung K8500. I'll make sure I can still return it if the M9500 comes out next month and looks to be any better.

There's nothing mentioned in here about the Xbox One S which I can't seem to find a conclusive answer on. Some people seem to think it does. This would make it one of the least expensive ways to grab a UHD player which works with the Playbar.

Any advice?

The Xbox One was an option so the One S might be. Only problem is that I don't think its HDR10 compatible so its only allowing you to watch 4k Blu-rays, which is fine except the whole reason we're jumping through hoops to find the right UHD players is that we're looking for an HDR10 and Dolby Vision compatible UHD player that transcodes DTS to DD 5.1 ... the holy grail for long suffering Sonos Home Theatre owners.

Regarding the Xobox One S - there's a post in this forum (forgotten which thread) that confirms the Xbox can downsample to DD5.1. He even posted the steps you take in the menu to enable this. Also, the Xbox One S does support HDR10. The question is whether it will ever get upgraded to also support DV.
In the meantime, I just got back from Costco where I picked up their version of the Samsung K8500 (UBD-KM85c) player. OI could have gotten it cheaper elsewhere, but they have a very liberal return policy. So, if the M9500 proves to be a big improvement I still have options.

Since purchasing my 4K TV last year this was my first experience seeing real 4K that wasn't being streamed (Netflix, Amazon). All I have to say is WOW!

My TV is a 65" LG OLED (2016). I put in the 4K version of Hacksaw Ridge. The HDR logo popped up when it started the movie, so I know I had everything setup correctly between the player and the TV. I was immediately blown away by the picture quality. Razor sharp and beautifully saturated. This is noticeably a much better picture than I have ever seen from Netflix or Amazon. The detail was amazing.

So, it saddens me that Sonos has stated that they are interested only in customers that stream all of their video content. Calling them "modern users". These users have no idea what they're missing. Heck I wasn't 100% sure about the difference until today.

I went into the Samsung's menu and set the audio to downsample to DD5.1 and it worked great. Under the "About my Sonos" it showed a DD5.1 signal.

So, I guess what I am saying to those of you like me who are trying to find the best player that'll still work with the Playbar, is don't wait too long. You're missing out 😃

Great news about the confirmation of downsampling on the xbox. I knew it supported HDR10, Dolby Vision would be great but I'm not put out without it. There's always the chance that the new software implementation could be released down the line.

I've got the Panasonic UB700 and it's a pain that it doesn't decode DTS. I miss that from my PS4 but the picture quality is something else on the player. My TV doesn't output 5.1 so is the option to use a HDMI to optical splitter?

I also had a Bose 300 when it first came out. It's not a patch on the Playbar. I thought the sound was a mess and it kept cutting out which required a reset. I returned it after a couple of days. To be fair, I didn't have the bass unit, which is meant to up the sound quite a bit.

Interesting info about the Soundtouch 300, because I am strongly considering that as an alternative to get past this DD5.1 issue. Curious if you had the Bose soundbar connected through WiFi or wired to your home network?
Can you elaborate on what you meant by "the sound was a mess"? I listened to the demo and Best Buy and thought it sounded pretty good - granted that was in a very noisy store.

I was the same as you. I purchased the 300 due to the DD5.1 issue on the Playbar. I also had a couple of demos of the 300 in the Bose store and it sounded great. It also looks fantastic which was a bonus.

I had it connected to my home network via WiFi, but for music it sounded very poor. Not a patch on a play 5 or even a play 1. I mostly wanted it to sound great with movies and again it struggled. The sound just lacked precision and warmth. I thought the sound also lacked depth and it was sold on the promise that it projects sound around the room. I didn't find that to be true.

My wife actually said it sounded no better than the tv. I really wanted to like it, but i couldn't get on with it. Maybe I had it all set up wrong, but it wasn't for me. Another factor could be that I don't like to listen to soundbars at higher volumes and the Bose could be one of those that comes to life at higher volumes?

Will one of the stores let you have a home demo to see what you think?
