Yes! If you want to dive deep you can read this older Microsoft document about it.
You no longer have to manually toggle on 5.1/7.1 support as that document claims, as they’ve hidden that option and made it always default to on.
If you’re using Windows 10, there’s a way to see if Windows Sonic is active on a current sound source. If you click the speaker icon in the system tray, you’ll see small text that reads “Windows Sonic for Headphones is currently in use” below the volume slider. The Xbox does not yet have a callout like this but I’m hoping they’ll add one in the future.
There was a period of time where not all games would properly send their surround data through to Windows Sonic, but support for this has grown over the last year or so and I’ve had far less issues with it than I had at launch. It’s designed to be a “turn it on and go” solution.
Both the Dolby Atmos app and the DTS Headphone app offer some additional options for EQ profiles if you want to get in and customize things a little.
There’s no harm in turning it on and trying it out for yourself. Thanks for reading!
