Spatial audio vs spatial “stereo”

I’m keeping this thread separate from another bug report thread related to the experimental drivers and their interaction with the TVOS15 spatial audio support.

This is a different issue related to spatial audio vs spatial stereo.

On the channels beta release with the default audio driver, there is no spatial audio support. I’m using latest TestFlight release and latest server prerelease.

When the experimental audio driver is enabled, I see something called “spatial stereo”. However, this is enabled for both multichannel Dolby digital material as well as stereo source material. However, I think TVOS in the channels app is only recognizing the material (even multichannel material) as stereo and that is why the OS within channels is only offering a “spatial stereo” experience and not the “spatial audio” multichannel experience.

I’ve verified on my setup that in other apps with TVOS15, I’m getting full spatial audio.
