Your streaming setup might be down-mixing Dolby Atmos, and this is how one can cease it
Whether it is a film or a playlist, streaming Atmos passes by way of your plan, your {hardware}, and an app setting earlier than it reaches your audio system or headphones. Any of them can drop it to five.1 or stereo, and also you won’t even discover at first.
Dolby Atmos is a surround format that lets mixers place every sound in three-dimensional house, overhead included. On streaming providers, it rides inside Dolby Digital Plus, a lossy codec, so even an ideal setup will not match the lossless TrueHD monitor on a 4K Blu-ray. It additionally is not the identical factor as Netflix’s spatial audio, a separate headphone function. And as a result of the Atmos knowledge sits on prime of a daily 5.1 or 7.1 combine, anything in the chain that can’t read it merely performs the combo beneath.
Your subscription decides earlier than your {hardware} will get a say
Ad-free does not mechanically imply Atmos
The first clue as as to if try to be listening to Dolby Atmos is the Atmos badge, and even that is not constant. HBO Max reveals Dolby Vision and Dolby Atmos proper on the title web page, whereas Netflix will not even present you the badge until you are a Premium subscriber and the gadget you are viewing it on (not my Mac) helps it, too. In different phrases, the badge is likely to be lacking even for those who’re paying for it. I could not discover the badge on Disney Plus, though I’m fairly positive we pay for the highest tier account.
Netflix requires Premium for Atmos, however neither the plan picker internet web page nor the pricing page says something about it. The necessities for Atmos could be present in a separate help article, which reveals the ad-free customary plan stops at “good” sound high quality. HBO Max requires Premium to get Atmos audio, and a few cable suppliers do not promote Premium, so chances are you’ll be out of luck for those who’re going by way of a cable system.
Amazon solely places Atmos on ad-free accounts, according to MacRumors, and the ad-supported tier streams Dolby DIgital 5.1 solely.
As for audio, Apple Music supports it in the standard subscription, and has a ton of Spatial Audio tracks, too. Amazon Music Unlimited has hundreds of tracks combined in Dolby Atmos, however requires the Unlimited tier subscription. Tidal supports Dolby Atmos in each particular person and household plans. Spotify, nonetheless, does not help Dolby Atmos.
Make positive you’ve the suitable tier to get Atmos; HBO Max Standard, for instance, is ad-free, however nonetheless does not allow Atmos.
Your TV is the almost definitely place Atmos will get flattened
Samsung’s help web page says that PCM outputs solely to left and proper channels, you will need to choose Auto or Pass-through at Settings > All Settings > Sound > Expert Settings > Digital Output Audio Format.
LG calls it Digital Sound Out, and LG itself says PCM limits output to two-channel audio; Auto or Passthrough each carry Atmos, and Pass-through skips the TV’s personal system sounds.
On a Roku TV, you will have to drop into Settings > System > Audio > S/PDIF and ARC, Auto pass-through may convert formats your soundbar doesn’t report as supported to stereo PCM.
Sonos says some TVs will not move Atmos even when the supply can, and usually re-encode it to Dolby Digital 5.1.
Your cables matter lower than you may suppose, until we’re speaking optical cables. Roku says optical is restricted to stereo PCM or compressed 5.1. Plain ARC cables work simply nice to decode the Atmos providers usually embed in Dolby Digital Plus, according to What Hi-Fi.
If you’ve eARC, it may be off by default, so chances are you’ll have to set it up to make sure it’s outputting Dolby Atmos.
Streaming bins play it protected once they aren’t positive
Mobile and computer systems depend on the apps
FIre TV will drop to stereo output if it does not detect Dolby help, although you possibly can nonetheless pressure Dolby Digital Plus. Roku’s quantity modes can pressure stereo, however you can even test Settings > Audio > Digital output format.
Apple TV 4k wants a path your TV won’t have, so you possibly can test to see in case your field is about to Dolby Digital 5.1, which re-encodes the whole lot to compressed 5.1, which does not embrace Atmos.

If your TV is ARC solely, you possibly can put the Apple TV into the soundbar’s HDMI enter as a substitute and see if that helps.
On telephones and computer systems, the app decides what you hear. Netflix supports surround on Windows, however solely in Edge or through the netlix app. Chrome lastly bought 4K however still lacks Dolby Atmos.
Netflix says you possibly can set up Dolby Access, then set Spatial sound to Dolby Atmos for residence theater or Dolby Atmos for Headphones underneath Settings > System > Sound.
Your headphones solely matter if the app can acknowledge them.
Further, your headphones solely matter if the app can acknowledge them. Apple Music’s Automatic setting performs Atmos, however solely with Apple or Beats Bluetooth headphones and choose built-in audio system. Wired or different headphones want Always On set in Settings > Apps > Music > Dolby Atmos.
Spotify does not supply Atmos in any type, so if it appears like spatial while you’re listening by way of your AirPods, it is probably Apple’s Spatialize Stereo is processing regular stereo.
Netflix does not do Atmos on headphones, however its sparate spatial audio function (Premioum-only) solely works with headphones from the model of the cell gadget, like AirPods or Beats with iPhones, Pixel Buds Pro with Pixels, and Galaxy Buds with Samsung Galaxy telephones.
Even with all of the fixes, you are in all probability nonetheless compromising
Streaming audio, together with Atmos, is not lossless by definition, even when all of the settings are right. Netflix additionally factors out that not each title on its service has Atmos in each language. With headphones, Atmos is a digital render, so sticking with the stereo grasp is sensible.
If you’ve a Sonos system, you possibly can usually discover if it is getting Atmos in Now Playing and About My System. Apple Music’s Now Playing screen will solely say Dolby Atmos in case your headphones (like these great Technics EAH-A1000s) are able to it.
Just keep in mind to work so as: test your plan, your TV output, your TV field settings, your cables, after which your app.
