DTS on LG series C for Sonos Arc

https://www.hdfury.uk/product/hdfury-arcana/

This is the hdfury you need 

LG 2021 tv is earc but does not support dts I guess that it is a licencing thing

I cannot comment on discs that are coming out in dts as i don't buy them anymore 

As for dts streaming I have not seen any information on it as dts does not interest me

The comment you included was just an observation to the other poster not you 😊

thank you again @skullc 

So, you were right and the LG 2021 has eARC. But as it does not support DTS, will the ARCANA solve the issue for PCM multichannel reproduction or I will get PCM stereo 2.0 ?`

Or using the feature on my 4k player that allows me to transfer any DTS sound as PCM will solve the problem as the TV will not receive anymore DTS but PCM ?

Think it will if you read the specs on the arcana it should tell you 

Good luck getting it to work 😊

With the C1, you will still have trouble with the UB9000/Arc alone no matter what settings you use on the UB9000 and the TV; it will always be Stereo PCM for any DTS variant audio disc. 

To get the conversion to multichannel pcm, I have a DR HDMI 4K device that allows the UB9000 and LG G1 to handshake properly and will send the converted data through to the Arc. This takes some manual setup on your PC to mess with the EDID stuff. I've heard the Arcana works for some as well and also that it doesn't after some update, but have not tried that myself. If you go either of those routes, I recommend putting the device between the UB9000 and the C1 so that all of your other devices (game consoles, etc) can flow through the C1 unimpeded.

If you sort the handshake problem between the C1/UB9000, the C1 will still report as multichannel PCM 7.1 always to the Arc, even for 5.1 mixes. I've heard mixed things about this, some say they lose 2 channels worth of audio, others say it sounds just fine. I still have not tested against a properly handled DTS variant mix, so can't comment accurately. It might be a "you don't know what you're missing thing".

The combo continues to he incredible for gaming (PS5/Xbox series x), Dolby audio discs and streaming movies/shows. Side note, the PS5 can be set up to report DTS variant audio as multichannel PCM 7.1 through the C1 to the Arc without the need of the little hdfury devices mentioned above...though you then won't get the quality of the UB9000 and it won't support Dolby Vision.

Regardless of the path you take, I wish you well! I spent entirely too long on this specific combo of technologies. I can't find a better combo out there for gaming, so I stick with the setup I have for now. I'm sure competitors will catch up...and offer their own combinations of problems in to the mix. In reality, there likely isn't and won't be a single setup that does everything you want the best which I have come to terms with.

@Rhz1971 This thread has gone a little astray. Let me try to simplify the information given and provide you the best options for what you are wanting to achieve:

If you want to keep your current TV, get the HDFury Arcana eARC adapter. This will allow your Blu-ray player to bypass your TV’s limitations and send audio directly to the Arc. This will allow you to get the highest quality audio from Blu-ray discs (Dolby TrueHD, Dolby Atmos, and multichannel PCM audio from DTS-encoded discs). I use the Arcana with a Panasonic UB820 player and an old plasma TV from 2013 and it works great.

NOTE: If you want to use more than one external media device with the Arcana, you will need to get an HDMI switch. This ROOFULL switch works well with the Arcana:

Purchase the Arcana from this link:

If you plan on getting a new TV equipped with HDMI eARC, an Arcana is not required. BUT if you plan on getting a new LG TV, there is a known problem with LG TVs and Panasonic Blu-ray players. With this combination, you CANNOT get multichannel PCM to play out of the Arc. So in this case, the Arcana would still be the best option even with a new LG TV.

But if you choose another TV brand that isn’t an LG, your Panasonic player should work fine with the TV and send multichannel PCM audio to the Arc.

If you get a new LG TV, you could use your Xbox to play Blu-ray discs instead of the Panasonic player, and the Xbox should be able to convert DTS to PCM and result in multichannel PCM audio. But this option would leave out your Panasonic player which I assume is your preferred option to play Blu-ray discs. The UB9004 is a fantastic Blu-ray player.

The DR HDMI 4K device mentioned above is another option, but as @Hebassaurus mentioned, it takes some effort to set it up correctly. The Arcana is a far simpler and more user-friendly option.

If anyone is based in/around Europe, can I also just throw-in this extractor/splitter device into the thread here aswell for consideration. This is an alternative to the Arcana Extractor & Splitter products …as this device from Feintech is a ‘combined’ solution that supports all the relevant codecs mentioned too:

I’m not affiliated to the product, other than I purchased and use one myself. It works well and so just posted here as a further device to perhaps consider. 

@GuitarSuperstar , thank you so much for your detailed answer. It is everything I was looking for. I will try the arcana ( first with the Panasonic UB9004 ). If it works as everyone says, I will then buy a switch to connect everything else ( Xbox series X, PS5 ). I was actually going to buy the new LG 2021 just because I love the LG performance. Sony Bravia is expensive and the Panasonic has poor software, as far as I have been reading. 

If you don’t mind, because I’ve been checking videos of Arcana setup but all of them are for the Apple tv 4k, I have a last question. The Panasonic UB9004 has two HDMI outputs, one for audio only. Currently it is connected to the LG TV by the normal HDMI Output. Once I have the ARCANA, should I connect the HDMI audio to the Arcana, and the normal HDMI output to the TV ? Or just the normal HDMI output to the Arcana and that’s it ( like if it were an Apple TV )

Until today, I thought my LG OLED 2017 had eARC, because it does support Dolby Atmos. When in actuality all 2017 LG OLEDs support for 7.1/Atmos/DTS:X sound is packaged in DD+ (Dolby Digital Plus) and then sent to external audio device (AVR or soundbar) to be decoded. So, this is not true eARC, just a way to get more channels over standard HDMI ARC. So probably I will get a boost in audio performance once I have the ARCANA. 

Again, @GuitarSuperstar, many thanks for your answer, also everybody else. It is amazing how people like you all are helping us in the best possible way to get the best of our setups. 

Just use the normal HDMI OUT (video/audio) on the UB9004 and connect it to HDMI IN on the Arcana. This is how I have my Panasonic UB820 connected and it works great.
 

In order to get lossless Dolby Atmos, Dolby TrueHD, and multichannel PCM audio from Blu-ray discs to play out of the Arc, you MUST have a TV with HDMI eARC (or Arcana). So, yes, the Arcana will give you a significant boost in audio performance from all of your Blu-ray discs. Personally, I think lossless Dolby TrueHD/Dolby Atmos sounds much better than the lossy Dolby Digital Plus/Dolby Atmos you get from streaming apps. And I think you will hear a significant difference between lossless multichannel PCM compared to lossy DTS Digital Surround.

One more tip: Since you are getting the Arcana, HDFury recommends using HDMI cables from KabelDirekt, Cable Matters, or Zeskit. I use these cables from KabelDirekt with the Arcana and haven’t had any problems:

But you should still use the Sonos-supplied HDMI cable that came with the Arc to connect it to the Arcana. The other cables are just to connect the TV and Blu-ray player to the Arcana.

I have a LG CX  with a panasonic ub820 4k player, and there was only one way i could get standard dts 5.1 surround from a older blu ray disc to work on my beam 2.

I did this using the optical out on the player, converted to hdmi (using the connector they supply) and going straight into the beam 2 and NOT the LG tv.

It means i have to pull out/swap the eArc cable from tv to beam 2, that is normally connected (which gives me atmos and dd hd), in order to get dts 5.1 surround from blu rays. But this is only on the occasion a fancy watching a older film from my collection.

I did it yesterday with valkyrie 2008.

Its a shame sonos dosen’t support DTS-HD though, i hope they do a update for it in the future.

Cheers m
