Hi All, anyone in here who got an hdfury arcana with the LG cx / ub820 / Sonos arc combo experiencing issues with cec/earc breaking when the arcana is plugged in after the latest LG update a few weeks ago? Whenever it is plugged in now the connection between the tv and the Sonos gets messed up, no cec volume control and no earc support. It’s infuriating!

I was looking into EDID emulators, and I was wondering if anybody had any experience with them.

 

I am curious about this too. Somebody over on AV forums just posted this:

 

 

“Download CRU : Custom Resolution Utility (CRU)
1.5.1 on top of OP

Extract and open CRU.exe

on the drop down list at the top, select the TV with soundbar plugged in (it should be marked as active)

on "extension block" slots there should be a CTA-861 - 3 detailed resolutions - 3 data blocks or something like that - select it and click edit

now select audio format and click edit

select LPCM > edit and check all sample rates and channels

click OK > OK > Ok

Reboot
Now PC show 5.1/7.1 chanels avaliable through HDMI and all is working great. I think it's EDID probblem with LG CX.”

So you can now get 5.1 and 7.1 through the pc or the Panasonic uhd player ?

Anyone in here owns the new Samsung QN90A tv and The panasonic ub820? Still having the same issues with getting PCM 2.0 instead of LPCM when connecting the player (with DTS set to PCM) and soundbar directly to the TV?

I've considered it. I'd like to avoid cable clutter, I run a very minimal set up and absolutely hate the sight if wires. Plus for the money I'd rather put it towards a device I'd get more than a singular use out of like the Xbox. 

Ya I briefly had the Arcana and it caused CEC issues and sound issues with my Shield, which I may have been able to work out possibly but even more infuriating was how the ports were setup so it was messy af to cable up and hard to place somewhere good where you could see the LCD but not look like absolute crap.  Was such a waste of time/money, ended up refunding it but they had to take out shipping cost so lost like $50 something out of the whole ordeal but I’d rather not kept the thing.

Fake surround is OK, but it's not really the experience that I was expecting from this system. I'm just waiting to get my hands on a Xbox One X, and the Panasonic will go up for sale. It's a fine player but it doesn't work with my system.  And nobody seems to be listening at customer support, we haven't seen a firmware upgrade in 2 years, I don't suspect we'll ever see one.

 

 

Hmm i have a Xbox series X and UB820. I certainly wouldn’t be jumping ship to play my movies on the xbox. Have you looked at any of the comparison videos from the likes of John Archer? The UB820 is still one of the best 4K players on the market and there is a considerable difference in image quality over something like an xbox/PS5.

 

The XSX also can’t and unlikely will be able to play dolby vision from 4K disks for some reason. Which is strange considering that they are moving towards dolby vision being used in games.

 

Yeah I'm aware of the visual downgrade, but I'm willing to accept that for proper surround. I've got a pretty massive blu ray collection (nearly 1500 disc's) and I'd like to be able to take advantage of the surround track. I wasn't aware of the lack of dolby vision, but I've really only got a few 4k dolby vision disc's anyways.  The Xbox will certainly be a bandaid until something comes along that checks off all the buttons. Or Sonos starts to support DTS... Whatever comes first. 

But why can’t you just use the HDFury? That way you get the best of both worlds

Have you set downmix to surround encoded on the Panasonic? Some time after the Arc was updated for better PCM support I put Divergent on and immediately noticed a vastly improved up mix with the DTS-X track with my Playbase. Not quite as good as the Atmos tracks on the sequels admittedly but very good. DTS-HD tracks needed a little bump in volume in the rear surrounds but still much improved. There must be some Pro Logic type of info the Panasonic is adding to the stereo output that Sonos wasn’t looking at previously. I’m not bothered by the lack of DTS support now and will be buying some more 4k release with DTS tracks that I put off buying. I was particularly pleased with 2001. The score sounded much better with the changes being mixed into the rear surrounds.

 

Ideally people would want to get LPCM rather than PCM for the best result but the TV is probably also a factor in that maybe?

Oh yes I've tried that, I've spent hours trying to find the magic configuration. The issue is an HDMI handshake issue between the Panasonic UB820 and the LGC9, the Panasonic literally won't pass the LPCM signal to the television. I've used other devices that can pass through LPCM / covert DTS to dolby on the fly (xbox) with no issue.

The thing is it’s not really fake surround its most likely using the technology Dolby used to put surround information in stereo soundtracks on 35mm film, back in the day, for those theatres that had their technology. Those that didn’t just got a plain stereo playback. The more I think about it the more likely I think it is that Sonos just wasn’t looking at the info in PCM sound that had it until after the Arc came out.

Question for the group.

I’ve followed the advice, set DTS to PCM within the UB820, plus set the downmixing to Surround, turned off Secondary audio etc. LG settings as standard.

The ‘Playback Info’ bar within the UB820 is showing DTS-HD MSTR, but within the Sonos app it’s showing as Stero PCM 2.0.

However, I am getting full surround sound across my rear SLs. With dialogue coming purely through the centre Arc. 

What do we think is happening here?

This is just a virtual surround, I had the exact same experience as you and documented it earlier in this thread. If your bluray has several audio tracks (like different languages) usually track 1 is English DTS - MA, followed by foreign language tracks in dolby digital 5.1.  Use the audio button on the remote to change the tracks on the fly and you'll very clearly hear the difference between a proper multi channel output and the virtual surround. I used the 4k of Once Upon A Time In Hollywood.

 

Additionally my LG C9 got the 5.00.30 update and I can confirm that it did not fix any of the hdmi handshake issues with the Panasonic UB820. I'm still getting 2.0 pcm instead of multichannel LPCM when outputing DTS.

I believe the Panasonic adds some surround info into the stereo PCM mixes and with the changes for the Arc PCM support they started using I think. Certainly my 4k blurays with DTS tracks seem to get a much better up mix than previously with my Playbase.

@JamesU2021 That’s interesting. Do you mind posting a screenshot of the Playback Info screen and the title of the movie you are testing?

@Surge My UB820 is connected from the HDMI audio/video out port to the HDFury Arcana and I get multichannel PCM audio playing out of the Arc.

 

I too am also getting 7.1 audio from the 820 through a DR 4K HDMI through my LG to my Sonos Arc. The only time I get 2.0 audio is when the source material is in 2.0 format.

 

After Panasonic asked for more info on my ticket, they have not further responded.

 

Hi I'm also getting 7.1 using the arcana. I've noticed today there has been an update on the c9. 5.00.30 not sure if it's anything to do with this though. 

 

Found this.

I’ve got a CX, not sure if there’s an update for me.

So I finally got around to putting in a ticket to Panasonic for this issue, and have received a reply which states the following:

“As I am aware, the player can only send the multi channel audio to an audio device connected via the secondary DHMI, Optical or Analogue connections (RCA).

However, I will send your query further to our technical department and will reply to you as soon as I have an answer.”

Can anyone here confirm if they have successfully gotten multichannel PCM out of the UB820 with the AV HDMI, either using an HD Fury or a different TV? I’m pretty sure what the support agent says isn’t true, but I would like someone to confirm that it isn’t true before I get back to them to state as much.

The bug that you are referring to is completely seperate the the post that was originally created, there are several other posts relating to the downmixing issue that cropped up since the LPCM update back in november. I would suggest keeping any posts related to it in a more relavant thread specifically raised about that issue

I returned the Panasonic UB820 unfortunately and replaced it with Samsung UBD-M9700 that I got brand new from eBay and Sony UBP-X800M2
I have two setups

  1. Samsung M9700 + Samsung LSP9T projector + Sonos arc ( 2 subs and 2 surrounds) 

DTS audio is RE-encoded on the fly to DD 5.1 so no issues with that. Dolby Atmos is passed through to Sonos arc (TrueHD or DD+).

HDR10+ is supported by M9700 and is supported by LSP9T. No Dolby vision but not a big deal because projector doesn’t support it anyway

 

  1. Sony UBP-X800m2 + LG CX + Sonos arc (1 Sub and 2 surrounds)

DTS gets converted to LPCM 5.1/7.1 - still have to deal with Sonos firmware bug with 7.1 as above.  Dolby is passed through 

Dolby Vision is supported for dynamic HDR. LG CX supports Dolby Vision.

 

 


 

 

Thanks for checking. I guess the firmware fix Sonos were working on according to their CEO for this issue is not a priority.
