Your streaming setup might be down-mixing Dolby Atmos, and this is the right way to cease it
Whether it is a film or a playlist, streaming Atmos passes by 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 may not even discover at first.
Dolby Atmos is a surround format that lets mixers place every sound in three-dimensional house, overhead included. On streaming companies, it rides inside Dolby Digital Plus, a lossy codec, so even an ideal setup will not match the lossless TrueHD observe on a 4K Blu-ray. It additionally is not the identical factor as Netflix’s spatial audio, a separate headphone characteristic. And as a result of the Atmos information sits on prime of a daily 5.1 or 7.1 combine, anything in the chain that can’t read it merely performs the combination beneath.
Your subscription decides earlier than your {hardware} will get a say
Ad-free does not mechanically imply Atmos

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, although I’m fairly certain we pay for the highest tier account.
Netflix requires Premium for Atmos, however neither the plan picker net 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 commonplace plan stops at “good” sound high quality.

Spotify, nonetheless, does not assist Dolby Atmos.
Make certain you could have the appropriate tier to get Atmos; HBO Max Standard, for instance, is ad-free, however nonetheless does not allow Atmos.
Your TV is the most probably place Atmos will get flattened

On a Roku TV, you will must 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.

If you could have eARC, it may be off by default, so it’s possible you’ll have to set it up to make sure it’s outputting Dolby Atmos.
Streaming containers play it secure once they aren’t certain
Mobile and computer systems depend on the apps

Netflix says you possibly can set up Dolby Access, then set Spatial sound to Dolby Atmos for residence theater or Dolby Atmos for Headphones beneath Settings > System > Sound.
Your headphones solely matter if the app can acknowledge them.
Further, your headphones solely matter if the app can acknowledge them.

Spotify does not supply Atmos in any kind, so if it appears like spatial whenever you’re listening by your AirPods, it is doubtless Apple’s Spatialize Stereo is processing regular stereo.

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 appropriate. 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 could have 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.
