OK I use this method to make audio in EN and UI languge in CN
1.Steam set game language to the audio language you want (etc. english).
2.go to bf6 root, ...\Battlefield 6\Data\Win32 copy 4 folders to desktop.
3.Steam set game language to the UI language you want (stc. schinese).
4.move 4 folders back to where they used to be, choose replace if file names are same.
5.Open BF6's Steam Properties - General - Boot Option (I think)
past "+miles_ language english"
change "english" to the audio language you choose in step one.
BTW I play AC Mirage in Arabic cause it seems neater. Thats why i want this option.
