I use a 5.1 sound bar with Atmos spatial sound supported. 3 channels from the front, with 2 speakers at the back, and 1 subwoofer.
I turn on Dolby Atmos spatial sound as well as the MSFS Audio Setting to turn on Spatial sound as well. It sounds sublime. I can hear all the sounds from around me including from above from the atmos placements.
But I don’t use it anymore, so I just use it as a standard 7.1 setup because I can’t capture the atmos sound for my Livestreams to YouTube. So I had to use the 7.1 so I can get all the sounds captured.
I use Mirilis Action, though. Not Nvidia since I need to Livestream in 4K HDR, something that GeForce Experience can’t do.
