I used Logitech Gaming System with a pair of G933 headphones and also Dolby Atmos for Headphones without problems during all past betas.
But so far I had to shut down LGS and end task on the Logitech Surround in Task Manager.
Now I was able to play at max settings smoothly for 3 hours non stop just running Atmos.
It seems to be a new issue with Logitech drivers in the release version of the game.
Just Google 'Division 2 Logitech sound' and see all the chatter.
I have yet to find an official post as to a patch, just the workaround.
As a related note, to get Atmos to work with my G933's I had to change the driver from the Logitech one to USB Audio Device.
Maybe this will allow anyone without Atmos to get surround to work in the game until a fix is made.
It will allow you to also select the Windows Sonic for Headphones that is in Win 10.
(Atmos is sold separately in Dolby Access in the Win Store)
Here are the directions from Dolby for changing drivers for the headphones:
The Logitech drivers interfere with the ability for Atmos to recognize the headset, however, there is a quick workaround that will still let you have full functionality from your headset and still use Dolby Atmos.
Please follow these steps:
Click your Cortana bar and type in: device manager
Scroll down the page that pops up, find an open "Sound, video and game controllers."
Right click on "Logitech G933 Gaming Headset.
Select Update Drivers
Click "Browse my computer for driver software"
Click "Let me pick from a list of available drivers on my computer"
Choose the "USB Audio Device" and select Next.
Finish the update and when it completes it may ask you to restart your computer.
After restarting you should be able to use your headset with Dolby Atmos for Headphones!
If you have any other questions or concerns, please don't hesitate to reach back out to us.
Have a wonderful day!
