Según esto solo se pueden hacer compatibles atmos y auro usando altavoces de altura y no de techo. Cuando usas atmos solo se oyen los FH y cuando usas Auro los FH y SH. (Ver imagen) Además indica que la voz de Dios es opcional.Auro-3D Speaker Setup
With Auro-3D, Front Height (FHL+FHR), Surround Height (SHL+SHR) and Top Surround (TS/optional) are added to a conventional 5.1-channel system to achieve a natural and realistic sound field that is three-dimensional and fully immersive.

After performing the Auro-3D upgrade you will be able to fully enjoy Auro-3D playback if you properly place the speakers for Auro-3D. Please note that Auro-3D does not support a Dolby Atoms configuration using Top Front, Top Middle, Top Rear, Rear Height, or any Dolby Atoms Enabled speakers. If you are using these speakers and want to take advantage of the Auro-3D Upgrade, you need to relocate them to Front Height and Surround Height speaker locations as shown above. It is possible to support both an Auro-3D and Dolby Atoms by adding Front Height speakers to a 5.1-channel configuration.
