Thank so much for your reports! An issue related to degradation of sound quality under certain conditions has been identified, and a fix is currently scheduled to be implemented in an upcoming patch.
In the meantime, there is an available workaround. Simply open up the Sound & Voice options menu,
un-check "Use Hardware," and then set the Sound Quality to "High." :)
