In the latest Apple MacOS Sequoia developer beta, a new option to bitstream passthrough of Atmos audio over HDMI is available in the TV App and others. What does this mean? How does it work?

Hope we can see it in action soon! I wonder how Atmos will sound on Apple.

[DCalderon]

You should try Apple Music Atmos to see if it’s lossless audio

[Nikita-P]

Thank you! I tried infuse with hopes to get bitstream for like Atmos or Trinnov demos I have on NAS…alas.

I’m curious what happens when you go to the midi settings. Can you now go above 8 channels? While not a huge deal it would be cool to see REW now able to send signals to all your channels as opposed the 8 channels it’s limited to now.

Stay on this - would be a game changer

Doesn’t Disney + have 6:30 content for you to test with?

[Manco]

I’m afraid you’re probably right… kudos on the fast video!

Hope this is ported down to TvOS where it's most needed. I love my AppleTV 4K but it's biggest downside is it being unable to passthrough any Dolby format to my AVR and doing all the decoding itself, sending the AVR just multichannel PCM.

Hey, when I use my Apple TV with a Sonos arc I noticed my audio is much lower than my in built lg g3 app. Do you think Apple will upgrade their audio with the Apple TV in OS18?

[SimonJonathanThorpe]

I just tried with the full version of Sequoia which has been available since yesterday. Using the HDMI connection to a Denon AVC-X3800H, which plays Dolby Atmos perfectly well via HDMI from an Apple 4K TV, the Mac output works for the AppleTV application in Dolby Atmos. However, Apple Music only outputs Stereo, irrespective of how the passthrough option is set. Very disappointing. The switch to Sequoia doesn''t seem to have changed things at all - Macs still can't output Dolby Atmos via HDMI.

looking forward to to trying it out with sequioa. I use infuse on my AppleTVs to stream mkv backups of my disc LPCM with auromatic is OK but passthrough would be welcome

[kenshinesca]

Why has passthrough taken this long. Would be great if truehd passthrough would work with the apple tv 4k devices.

[kenwilcox]

It would be nice if they would bring 4k downloads with this update.

[Leo-tfgu]

Wonder how much Dolby D+ to TrueHD difference is? Probably 5-10% noticeable.

[Randy_Solares]

Great news nonetheless, I wonder if Infuse will play Atmos through Mac now?

[JoshHare]

Great video, I think only the MacBook Pro M2 onwards supports multichannel audio out of the hdmi output?

[mpitogo]

lossy is probably because it is from a stream, lossless you will need an mkv backup from a disc

HELP? I am running a 2014 Mac mini into a Bose V30 surround. The Mini does not recognize that the Bose is 5.1 and only allows me to output stereo. How can I get 5.1 set up on the Mini? Either software or a hardware device between?
Thanks, been fighting this fight for years now.

[PIPERBOYWILLIAMS]

How do I get I touch with you ? Have an anthem question before my return window is over

[AlessandroPinto-bggy]

Hello, the official release of OS Sequoia of two days ago, contains HDMI passthrough? I didn't found any official news and Apple Support I called from Italy confirm is not present. Could you give us information about that? Thank you.
