r/Dolby

Bonjour à tous,

Étant gros consommateur de musique surtout depeche mode, j'aimerais savoir comment supporter du dolby atmos sur les distributions Linux.

Ainsi que l'installation d'une chaîne hifi des années 80 une kenwood en dolby prologic.

J'ai acheté des enceintes premium des Colonnes hi fi MORDAUNT SHORT MEZZO 8.

Je vous assure qu'avec sa l'écoute musicale est top.

Donc si quelqu'un peut me donner des informations du style quelle configuration pc pour faire tourner tout sa sur du linux.

N'importe quelle distributions, je me débrouille assez bien dans tout ce qui est tech, et j'ai sauté le pas de linux début 2026 avec zorin, Kubuntu, mint.

Voilà merci d'avance pour vos retours.

Hey guys,

I’m really I can get some help here.

I recently just bought the Hisense ax5140q sound bar which is a 5.1.4 system with Dolby atmos and DTS:x support etc.

Now I’m new to all of this so I have no idea how it all works but I am trying to learn.

I have this soundbar plugged into my LG B5 OLED tv via eArc.

I tried pass through but tbh the video downgrade is not pretty.

I watch primarily Blu-rays and some streaming.

I watch these through my Xbox or PlayStation but no matter what I do I don’t know what options are best or get the bloody thing to work properly.

I have my tv set to “pass through” and “allow pass through” on my Xbox.

I have set the format to “Dolby atmos for home theatre”

But when I play a movie it sets it on my sound bar to “Dolby MAT”?

I have also tried the option of “let my receiver decode”

Which I’ve heard is the best option because the Xbox sends the raw file to the sound bar to let it decode the audio format. HOWEVER.

Every time I do that and try to play a movie it says that’s my receiver can’t decode it? But it’s a atmos supported or DTS sound bar?

If you have a Dolby atmos/DTS sound bar into a LG Oled what is the best settings and options? And why won’t it let my sound bar decode it?

I should add I’m using a certified super fast HDMI2.1 cable.

Also, the audio sync is always slightly off? The only way I can get it to be in sync is setting it back to 5.1 uncompressed on the Xbox but then that sets the sound bar to PCM, NOT atmos?

I’ve tried delay on sound bar and on the TV but seems to do nothing, PLUS if I do change it, it will then make things other than the movie WELL out of sync.

So where I’m at is it seems like I can’t have atmos on at all? Even tho I got it for that reason?

Please can someone give me advice because I’m loosing my mind and I don’t know what else I can do, I can’t return the sound bar now so I wanna get it right, because the actual quality of the sound is really good!

Thank you for any advice

I’m A/V Geek, travel from Mumbai India to London UK to experience 5 different formats.
After watching The Odyssey in 5 different formats, I finally have a pretty good idea of how much the presentation changes the experience.
My ranking is based purely on my personal experience of picture, immersion, colour, dynamic range and sound — not simply on which format is technically “superior.”

🥇 1. IMAX 70mm (BFI IMAX) — the best overall experience
Immersion: 10/10
Picture: 10/10
Colour: 9.5/10
Dynamic range: 9.5/10
Sound: 8/10
This is still the king for me.
The 1.43:1 IMAX presentation completely changes the scale of the movie. The image fills so much more of your field of view that it genuinely feels like you’re inside the film rather than watching a gigantic screen.
The 15/70 film presentation has an incredible organic sharpness and texture. Colours look very natural and the image has that unmistakable large-format-film character.
My only criticism is the sound. It wasn’t bad at all, but compared with some of the premium digital systems I’ve experienced, I found the audio less impressive than the picture.
Overall: 10/10

🥈 2. Dolby Cinema — best digital presentation
Immersion: 8.5/10
Picture: 10/10
Colour: 10/10
Dynamic range: 10/10
Sound: 9.5/10
This was probably the most impressive digital presentation I’ve seen.
The contrast, blacks, highlights and colour volume are fantastic. Dark scenes in particular look incredible.
The main disadvantage is the framing. Depending on the Dolby auditorium, you’re watching the film in a flatter or wider presentation rather than the full 1.43:1 IMAX frame, so you don’t get the same vertical immersion as IMAX 70mm.
And one correction to something I’ve seen repeated online: The Odyssey does not have a native Dolby Atmos mix. Nolan’s theatrical soundtrack is based around a 5.1 mix, even when the film is presented in a Dolby Cinema auditorium.
So for me, Dolby wins on digital picture quality, not because it has an Atmos mix.
Overall: 9.5/10

🥉 3. Standard 35mm film (Barbican)
Immersion: 8/10
Picture: 8/10
Colour: 8/10
Dynamic range: 7.5/10
Sound: 8/10
Still a great experience, but once you’ve seen the full 1.43:1 IMAX 70mm presentation, the difference is obvious.
The wider framing makes the movie feel less enormous and you lose that incredible vertical IMAX composition.
It’s still film, and there’s something special about seeing The Odyssey projected from a physical film print, but for this particular movie I think the format sacrifices too much of what makes the IMAX presentation special.
Overall: 8/10

4. Vue EPIC — surprisingly beautiful
Immersion: 8/10
Picture: 9/10
Colour: 9.5/10
Dynamic range: 9.5/10
Sound: 7.5/10
This one surprised me.
The colour and dynamic range were excellent. In some scenes I actually preferred the look to standard digital IMAX.
It doesn’t have the sheer physical immersion of IMAX 70mm, and the audio wasn’t as impressive as the best IMAX/Dolby auditorium I’ve experienced, but visually it was a very pleasing presentation.
If someone told me they couldn’t get to an IMAX 70mm screening, I’d absolutely recommend trying a good EPIC auditorium rather than just going to the nearest standard screen.
Overall: 8.5/10

5. IMAX Digital — good sound, disappointing picture
Immersion: 7.5/10
Picture: 6.5/10
Colour: 7/10
Dynamic range: 7/10
Sound: 9/10
This was probably my least favourite presentation.
The large IMAX screen still gives you that sense of scale, and the 12-channel IMAX sound system can be seriously impressive.
But compared with the 70mm film presentation and Dolby’s digital projection, I found the picture noticeably less impressive — particularly in terms of sharpness, contrast and overall image quality.
The funny thing is that the sound was one of its strongest points.
Overall: 7/10

Curious to hear what’s your ranking?

Some IMAX screens are film, some are laser, and some are DLP. They range from 2K to 4K, and have to compromise when they project 3D. Are Dolby screens more standardized than IMAX?

Is every Dolby screen a 4K laser projection with overhead speakers? In the case of high frame rate movies, are they always that way, or are some screenings 24 FPS? Are there any compromises for HFR or 3D screenings like a lower resolution or dim picture?

Thanks.

Hey I have the Samsung Q990c. Plays full Dolby atmos. I purchased the new Mandalorian movie.
It’s starts out sounds great even says it’s in Dolby atmos. After about 30 seconds it changes to Dolby digital plus and sounds like dog shit. Is there a way to make it stay in Dolby atmos??

Muy bien

Hablando de películas de su calidad y sonido

¿Cuál es mejor para disfrutar en una pantalla de gama media/alta?

1080p o 4K

Experiencias?

Imagen en 4K que les ha parecido?

Imágen en 1080p que tal?

Sonido en ambos cuál es mejor?

For those of you who saw it in Dolby, would you recommend it audio wise? I saw it at a regular theater and it sounded good but I want to rewatch it and I was considering watching it with Dolby Atmos, here in my country we don’t have Dolby cinemas but we do have some theaters with Atmos. Is it worth the price of the ticket? I’ve heard sometimes marvel movies don’t have great Atmos mixes, but some others do. Would you recommend it? Thanks! (Also if you do recommend it, what are some moments that stood out for you regarding the audio?)

Hi everyone!

I’m considering getting a Sonos Arc and adding Sonos Era 100s as rear speakers.

I’m particularly interested in the Dolby Atmos experience.

For those who are actually using an Arc + Era 100s surround setup:

* Does the Arc + Era 100 setup properly support Dolby Atmos?
* How much does adding the Era 100s improve the sense of immersion and 3D/spatial sound?
* Does it make a noticeable difference in the height effects or overall Atmos experience?
* Would you recommend adding the Era 100s if my main priority is getting a more immersive Dolby Atmos experience?

I’d especially love to hear from people who currently use this exact setup.

Thanks!

I haven’t seen it yet and the theater has large Dolby and imax screens. Which is the better experience . I usually live in Japan and I haven’t been to a Dolby cinema in the USA In years. The Japan Dolby screens ones are kinda small with weak bass so I usually only go to imax there. Wondering if worth the Dolby experience here vs imax.

Edit: It would be a smaller 1.85 Dolby vs a very large scope Dolby vs 1.90 IMAX

Tengo la duda sobre como funciona el Dolby Atmos de apple music en Android y si es inferior a la version de IOS o a otras apps que usan Dolby AC-4 para Atmos

Hi, I have a samsung Q990F, I am having issues with its dynamic range being too loud at moments, even with the night mode turned on (i can barely tell a difference tbh)

I was watching the movie “the woman in cabin 10” on netflix with dolby atmos and there was this scene where the protagonist goes to sleep, and she suddenly has a nightmare, there was a scream SO FREAKING LOUD it woke up the whole damn house, it probably woke up the neighbors too.

I was watching with the volume on 16, its a comfortable level for the dialogue except there are a few scenes where it gets insanely loud. Its the same with all movies really. I have to watch them with the volume on 10-12 in fear of sudden loud noises that will shake the house up, but then the dialogue is too quiet.

Anyone else has this problem? Anything i can do?
