Page 11 - Onboard Sound (RMAA 6.2.3) Analyzation
ASUS advertises its onboard audio as "ASUS Crystal Sound" on the P8P67 PRO with the Realtek ALC892 high definition audio codec. As discussed earlier, this is the improved version of the Realtek ALC889. Let's see how well it performes in our RightMark Audio Analyzer tests.
