Like with SBX always use speaker modes. I don't have BF1 but there should be a speaker/surround setting. Never use headphone modes with SBX, GSX and Co. Always treat those solutions ingame like speakers. That's what they actually do, you know.Virtualize a 5.1/7.1 speaker environment. Except in the case of Dolby Atmos in combination with games that offer real Atmos geodata.
