Downgraded Windows 11 to Windows 10, formatting everything at the same time.
Sounds are perfectly normal now (game is in stereo), still don't know what was causing the issue that game was forcing 5.1.

Its like DayZ would be set to 5.1 surround sound, tried changing stereo to 5.1 surround in CSGO and get same results like in DayZ right now (sounds behind are very quiet), but in CSGO I have an option to go betwen 5.1, 7.1, stereo etc. in DayZ I don't have that option.
Can I force the game to be in stereo somehow or is there a hidden setting or whatever?
