Thank you for your reply.
I don't have a desktop, is a customized laptop and the board is this one W35xSTQ_370ST
I've contacted the guys that mounted my laptop and told me that I have a Realtek audio card, so I don't know why when I install the Realtek drivers, Windows still use their default drivers.
I am afraid Intel does not provide drivers for Realtek cards. You need to contact the board manufacturer for driver downloads or system vendor for assistance.
Yes, they do, in the Intel download center there are Realtek drivers (none works for me).
