Thank you for all the answers.
I think if nothing changes I will try the forced update in the next weeks (it is not simple because with the microsoft high definition audio driver the sound of the microphone is so low that the other people almost not understand what I say and of course listening to music or just a video is sounds worse than with the conexant driver.)
Are you sure that if i reinstall the conexant driver to the new win10 (which probably will be the 20H2) it will work good? (I mean the sound quality and the windows too)
