Dolby Atmos Theater won't work anymore since last Skip Alpha update.

Hello!! I'm in the alpha skip ahead. With the last build the problem is fixed. Now it's multichannel in the dashboard, when you load an atmos game the display will change in atmos. Same for netflix.

This is fantasic news! Thanks. So just to be clear it seems that Microsoft solved it? Or did Dolby Access get an alpha update?

I have the same issue since the latest alpha update that was released October 27th. Before I had bitstream out and dolby Atmos. Now only 7.1 PCM.

But my blu rays are working with dolby Atmos. I hope this get patched with the next update.

So after following up with the Dolby Access support team, apparently games aren't supported on home theater, only on headphones:

"Unfortunately, Games encoded with Dolby Atmos audio are not compatible with Dolby Atmos for Home Theater, as they are specifically configured for Dolby Atmos for Headphones. If the content you are experiencing is not compatible with the app you are
using, then audio will cease, or will simply output as regular stereo output.

To clarify, Dolby Atmos for Home Theater is included at no charge with any Dolby Atmos supported hardware, such as a receiver or Xbox One X, and is used to activate Dolby Atmos features via HDMI connection for a Dolby Atmos certified AVR, soundbar,
or TV."

"Unfortunately, the version of Dolby Atmos included with your Xbox is Dolby Atmos for Home Theater, which is not compliant with any gaming content."

It kind of strikes me as hard to believe, or that this won't be addressed, but that's what they're saying for now. That said, it still isn't working for me for Netflix content either, so I'm going continue troubleshooting with them and see what's doable
and what's not. Fingers crossed.

According to the Latest Alpha skip ahead Insider release notes this is still an issue the engineers are tracking and working on.

Hi have you contacted support over this? My one x updated fine I've had the update for a month or two now with the alpha skip ahead release, and the only issue I seem to get is that the dolby atmos app sometimes needs redownloading for the system to recognise
it but then it works fine for weeks.
