I'm trying to learn as much as I can about how audio on Xbox One works and, since I read that Xbox One will soon get Atmos upmixing, I want to learn about that as well, and I'm searching this thread for the word [upmix] and am reading the posts that appear as results (and also some of the posts that are responses). Here are a few that I want to respond to:
Does anyone have the upmixer yet? If so, is it simply the Dolby Surround upmixer--the same Dolby Surround upmixer that Atmos-equipped AVRs have--or is it something custom?

I believe the Battlefield series also does 5.1 on consoles.

So, Dolby Labs changed its mind again recently to allow Atmos upmixing on non-Dolby tracks. So, we 'd expect to see that come back to Xbox ASAP. Not really impressing back in the days. Not really expect to see much difference with the new update.
I only wish it can upmix 5.1 PCM game audio (majority of games are 5.1 audio) to 7.1 first before upmixing to Atmos. I have a 7.1.2 setup and hate to see two silent rears whenever I switch to Bitstream Atmos.
So DaverJ says that most games have 7.1 audio, and Foxbat121 says that most games have 5.1 audio. Which of those two statements is true? If you can be platform-specific, please be platform-specific: Xbox One, PS4, Xbox 360, PS3, Switch, Wii-U, etc.
I wonder if there is a site like shotonwhat.com, but for games.
Foxbat121: Would you mind updating me on this: when you switch to bitstreaming Atmos, and play a game that has 5.1 audio, are your surround-back speakers still silent? What about Netflix and other media apps (and what plan(s) do you have for those services--HD or UHD)? Are you an Xbox Insider? Beta or Alpha?

My X1S is setup to bitstream Atmos to my AVR and my speaker setup is a 5.0 setup. When I'm using my Xbox, my AVR says that it is receiving Atmos, 48 kHz, does not mention PCM, number of input channels, bitrate, nor dialog level. Two of those things that it doesn't give me are things that your AVR gives you: yours says PCM and the dialog level. Why does yours show the dialog level and mine doesn't? I have passthrough bitstreaming for DVDs and Blu-rays enabled, and when I play a DVD or a Blu-ray, my AVR momentarily shows me a dialog value, but not when I'm doing anything else on my Xbox. In the thread how do Dolby Atmos and DTS:X work on Xbox One
, Foxbat121 and I discuss whether Xbox Ones pass along Dolby metadata from sources such as Netflix and VUDU, and my impression is that they don't. If you have any information that you can add to that subject, please visit that thread.
