LG C9 + Arc + UB820 / Multichannel PCM for DTS Blu-Ray discs

I have this same problem, LG cx - ub820 - beam v2

Called panasonic today, no luck

Called sonos today, no luck

Sonos say that i have to go through the tv to get dts, but as you all know LG cx not compatible with dts!

Tried all the above settings and i cant get the 820 the give out dts?

I tried the PS4 with a blu ray dts, and it came out on the S2 iphone app saying multichannel PCM 7.1 !!?

I guess i will have to play my big collection of DTS films through the PS4 then, if i decide to keep the beam?

Its a real shame i can’t get the panasonic to play them though given the better tech it packs over the PS4!

Since the LG CX cannot pass through DTS audio, your only option is setting the Blu-ray player to convert DTS to PCM so you can get multichannel PCM audio (which sounds better than DTS Digital Surround). Or you can get the HDFury Arcana so your Blu-ray player can bypass your TV’s limitations.

To get multichannel PCM audio from DTS discs, be sure to set the DTS/DTS-HD setting on the UB820 to PCM. It’s best to turn off the Secondary Audio feature too.

Hello mate, i did try changing the dts to pcm but i got nothing, this has been driving me mad for days!

Would this Hd Fury Arcana allow the beam 2 to accept DTS-HD ?

No Sonos product supports lossless DTS-HD Master Audio or DTS:X. Sonos only supports lossy DTS Digital Surround audio.

But, yes, the Arcana would allow you to play DTS Digital Surround or multichannel PCM from DTS-encoded discs. I use an Arcana with my UB820 and it works great. Multichannel PCM audio sounds just as good as DTS-HD Master Audio.

Thanks for the reply G.S, first off what does lossy mean? 

Also my PS4 is playing the dts blu rays through the beam2 at multichannel pcm 7.1, is this format better than dts surround anyway??

I wonder what the steps in sound quality are, from the worst to the best???

I.e from basic phono stereo to atmos/dts-x? including this pcm? lpcm? dolby digital, dd+, truehd, dts surround, dts-hd ect. ect.??????

Please educate me anyone…..

Thanks m

@mac74 Lossy is a form of audio compression that results in some audio quality loss from the original recording during the audio conversion. Common lossy audio formats are Dolby Digital, DTS Digital Surround, and Dolby Digital Plus. These formats are commonly used on DVDs and streaming apps like Netflix and Disney+. Because lossy audio is more compressed, there is less audio data which allows it to be streamed or put on a DVD.

Lossless is a form of audio compression with no loss of audio quality from the original recording. Common lossless audio formats are Dolby TrueHD, DTS-HD Master Audio, DTS:X, and LPCM (or multichannel PCM). These formats are commonly used on Blu-ray and UHD discs because they can hold much more data than a DVD.

Dolby Atmos audio can be delivered through three different audio codecs:

1. Lossy Dolby Digital Plus (streaming)

2. Lossless Dolby TrueHD (Blu-ray)

3. Lossless Dolby MAT (used on Apple TV 4K, Xbox One X/S)

Lossless audio is higher quality audio than lossy, so lossless multichannel PCM is better quality than lossy DTS Digital Surround on your PS4.

Some home theater enthusiasts prefer a certain audio codec over another, but all lossy formats generally sound the same in quality, and all lossless formats generally sound the same.

Many thanks G.S, thats good to know that.

I have got the pananonic 820 to work with the beam2 now!

It was the hdmi lead!   ????

Optical out on the player, to hdmi converter into the beam2. Selected bitstream on all the output settings, and secondary audio to auto, and surround encoded in the pans menu. And dts surround 5.1  !!!  Great!

So is dts surround 5.1 out of the panasonic direct to beam2, still less quality the the ps4’s multichannel PCM 7.1 which goes via hdmi into the tv then out of the tv into beam2???

Why are you using optical out on the UB820? Optical doesn’t support lossless audio including multichannel PCM audio. You should connect the UB820 from the HDMI Video Out to an HDMI port on the LG CX.

Yes, DTS Surround 5.1 is lower quality audio than multichannel PCM 7.1.

Its the only way way to get dts out of the player BECAUSE of the LG tv! The other hdmi audio out port on the 820 wont work direct into the beam, so optical is the only way. Dts surround 5.1 sounds a lot better than the stereo pcm 2.0 i was getting when going through the tv anyway.
