Does this game do regular dolby digital 5.1?

Atmos is usually backwards compatible with DD, but I don't have an atmos reciever, so I can't set up Atmos on my PC.

Is there a way to get the game to output Dolby Digital 5.1?

My surround system is a Sonos Beam with surrounds. It only accepts Dlobly Digital 2.0 or 5.1 and PCM 2.0. So it does not accept 5.1 PCM. My TV accepts Dolby Digital and passes the stream to the Beam.

From what it looks like, set your Windows sound output to 5.1 channels and set RotTR in-game to spatial sound. Windows 10 can do native surround encoding, and assuming it correctly detects that your system is DD capable, it should output properly.

Note that this is "should" - there isn't a lot of documentation on this. Theoretically Windows Spatial Sound only supports Atmos according to MS documents, but also, according to other documents about the audio stack, Win10 should reencode surround sources dependent on the detected device over HDMI or force into 5.1 over TOSLink. If I have a chance, I'll test it this weekend.

Edit: Below is my original response, which does not actually apply to RotTR it seems, as they are using a Microsoft API to generate spacial sound. I left it because it's still a viable workaround to connect a PC or HTPC to an older reciever and force reencoding.

Atmos actually isn't really compatible with DD5.1 - it's compatible with DD True HD, the difference being standard DD is compressed audio and the latter being uncompressed.

The Sonos doesn't seem to support DDP or True HD, only the older lossy DD.

Windows should convert and resample Atmos/TrueHD/DDP to DD5.1, even if they pulled what Netflix did with DDP. Microsoft was kind enough to build that into the OS this time around.

It will depend on how you are connecting the TV - if via HDMI, and the TV isn't telling the PC that it needs a DD5.1 audio stream, Windows is going to push Atmos/True HD, and if the Sonos can't handle the uncompressed True HD (spec-wise, it doesn't look like it can) stream, it's not going to work.

In that situation, if you are having issues, your only workaround would be to either use optical output from the PC (this forces Windows to reencode the audio) or an HDMI audio extractor box that lets you select 5.1 for the HDMI device data.

You failed to mention that you have your sound being passed optically from your tv to the Sonos. You need to have it configured via hdmi to the Sonos then OUT to the tv, otherwise you'll run into playback limitations.
