macOS Sequoia Supports HDMI Passthrough for Dolby Atmos Content

Help get (more) Dolby Atmos on Apple TV

Update 2/10/20: Infuse now supports Dolby Atmos when using E-AC3 audio tracks. Dolby Atmos support has been announced at WWDC for tvOS 12! Unfortunately, the current implementation is only useful for VOD services like iTunes, Netflix, and Vudu. Enabling Atmos for (most) local content is a change that needs to come from Apple, and as the old saying goes “The squeaky wheel gets the grease.” So…we’re asking you to be as squeaky as possible…within reason of course. Ways you can help Request a f…

Unfortunately, the ball is on Apple’s side. Until they give access to the sound bitstream, the infuse developer will not be able to do anything.

Have you an idea why Apple makes the decision to allow lossy and not lossless, now i used a extra device to play lossless content from my mac o the AVR so for me extra cost, more energie not sustainable one of Apple’ s goal, i can not believe it is a hardware question only more bits?

Bitstream audio interferes with the work of talking Siri. And this is Apple’s proprietary service. He’s a priority. Apparently, Apple has not yet come up with a way around this problem.

Thanks something new for me this information. And lossy is now problem for Siri and lossless is the bottleneck?

[Axl2021]

No. Audio in the bitstream is a problem for Siri. And for Dolby Atmos in TrueHD, you need a bitstream.
If Apple adds bitstream support, Siri will stop working.
And knowing how Apple treats its own services, I’m sure that bitstream support, and therefore Dolby Atmos TrueHD, will never be on board their devices

Tanks again but ??? Dolby Atmos lossy is also a bitstream and now with Sequioa and a Silicon Mac you can play or stream Dolby Atmos from the Mac in three apps from Apple these content and equals now nearly of complete the possibilties of ATV therefore my question the difference between lossy en lossless in interferencing Siri

Hello

For me is this an eyeopener. Never thought about this. And maybe you can imagine I want to know more. Ok I have heard before that bitstream can arrange errors, though they are only zero’s and one’s. I have asked ChatGPT about this and I get complete confirmation about lossless, not fully about lossy. Apparently has Apple found a solution for the lossy bitstream. May I ask Who is the source of this information, google between bitstream interfering Siri gives no result it like to be not only for me a revelation but surely for more people, many many thanks for clearing up

No official source. Just a logical deduction about the most likely reason. Another possible reason: Apple does not sell lossless soundtracks, and no one streams them, so they haven’t bothered to enable it.
