LPCM not addressed in 12.1. Still open.

Ok so my lpcm is being compressed into something the Sonos can decode. Sweet.

Your TV takes in LPCM (or Dolby MAT because I think that’s how Apple TV sends Atmos), compressed to DD+ probably, and sends it to Sonos (you should see in Sonos app what format data it’s getting).

for me Atmos was never a problem (LG C9), it’s the 5.1 content that is being flattened to 2.0 :(

I got the physical Apple TV and Dolby on new firmware. Guessing via pcm not lpcm. Is that correct?

Badge

Oh I see. PCM works fine after LG firmware just not lpcm for high sq and Sonos need to fix that as promised. Is that correct.

I am still waiting for the LPCM update, as it enables higher sound quality than compressed Dolby. People like me, who use an Apple TV, can get either Dolby Digital 5.1 or LPCM. I want Sonos to support the latter, because it enables higher fidelity sound!

Badge

Yes me too. I am not sure how the Sonos is doing PCM if it does not support PCM but don’t care as the atmos Dolby sign is displayed and I am now happy. 

come on LG Europe pull your fingers out and release the UK firmware that fixes this.  Yes I know this is a Sonos forum, I wish LG UK has a forums and I’d post over there.

hi @Bertybassett 

LG released an update last night for 2020 Nano in Europe and now i get dolby atmos from apple tv 4k with sonos arc.

It’s also off-topic. This thread is about LPCM support on Sonos Arc. Nothing to do with LG...

So I decided that I'm returning my Arc.

It didn’t make me fall in love with it, because of the silly issue here described, and I feel that €900 speaker really should. 

I may consider revisiting this when LPCM is supported, but not gonna hold my breath.

Badge

yes and it will be blocked from loading on your TV.

The USA version of the firmware more than likely is region blocked.

I’m sure the firmware is actually different. The US has a completely different broadcast TV standard than the UK, for one thing.

Any update on the LPMC would be most appreciated, just got Arc and I’m very disappointed it doesn’t support it :( 

Same here. How on earth was this not integrated to begin with??

Considering a return.

Badge

because LG are rubbish!  Say what you want about apple but that would never happen in their world.

@Bertybassett 

I have checked a few of the European sites and they are all .28 as you and I are.  I do not understand why it takes so long to roll out to us.  I wished we could just load the US firmware but I would be afraid of bricking my tv.

Ok I’d best stop pressing update every hour.  

Had to laugh when I saw this. I have been doing the same thing in Germany.

Nothing for the U.K. version of the nan906 yet. 


It takes a long time to localize the US version for the UK :laughing:

I’ll just have to keep pressing the update every hour until they release a U.K. firmware.
