Si ca peut te rassurer, j'ai le même problème que toi, plus aucun son mais nous sommes nombreux à avoir ce probleme, voici ce qu'à dit un des devs :
"Hello guys!
We are sorry that the recent hotfix, intended to fix several serious issues for users, has also introduced a new bug that breaks audio for many of you.
We are looking into it and will have a fix out as soon as possible."
