I've tested multiple different in-game settings. I've tested multiple headphones and multiple sound configurations in Windows 11. None give me the result that allows me to play by sound.
They aren't loud enough. The positionality is terrible, I can't tell how far away they are and I can only vaguely understand the direction, rather than precisely being able to pinpoint the location. The sound is drowned by other sounds far too easily. Even when it's quiet, you still can't reliably hear other people run.
To make matters worse, they added this shellshock effect that makes you temporarily deaf. Especially when there's a lot of things going on. Battlefield 2042 had this nonsense too, but at least that game had excellent positional audio.
