HI I have fond the fix. So for me the problem ocurred when I upgraded my windows from 10 to 11. The fix for me was uninstall video card drivers and sound card drivers. After that you have to Reset (not restart) the pc. To do that: In search box write "Reset my PC" after that you press "Reset PC". Choose to keep all the files,when it is done,reinstall the drivers for videocard and audio and it worked for me. I was not having sound since november 2022. But I tested it last night and people could hear me,also the " ) ) " at the in game mic appeard. Pardon my english ! :))
