when I plugin headphone and mic on thunderbolt 3 port, it dosn`t working . how I can fix that ?
There’s no such thing like thunderbolt port. There are thunderbolt controllers and thunderbolt docking stations. There is USB-C port and a lot of things behind it (one of them thunderbolt controller, for example). So, you have to inspect to which controller your headphones and mic are attaching to when attaching to USB-C port in order to further diagnose it.
Probably some sys-usb has to be involved here.
