În decurs de câteva zile ASUS a anunţat două noi plăci de sunet, Xonar DS 7.1 şi Xonar Essence ST. Prima este destinată pasionaţilor de jocuri ce doresc o calitate a sunetului mult peste ceea ce oferă sunetul integrat în plăcile de bază la un preţ accesibil iar a doua are ca ţintă entuziaşti şi audiofili pentru care calitatea sunetului este pe primul loc. ASUS declară că noile plăci de sunet oferă un sunet de 12 ori (Xonar DS) / 64 ori (Essence ST) mai clar decât orice altă soluţie integrată.
