Audio

Producenci testowanych przez nas płyt głównych mają odmienne podejście do kwestii audio. ASRock i MSI podeszli do tego wzorowo oferując nowe kodeki, natomiast ASUS i Gigabyte pozostali przy sprawdzonym, ale już lekko wysłużonym Realteku ALC892. Oczywiście różnica między obiema grupami nie jest ogromna, ale w tym przedziale cenowym tego typu zaniechanie nie jest zbyt dobrze widziane. Co ciekawe jednak, pomimo tego, że MSI postawił na bardziej rozbudowany system audio, jakość dźwięku jest w jego przypadku najgorsza, co pokazują też poniższe testy. Poniżej znajdziecie cztery tabele z wynikami poszczególnych modeli. Oczywiście tak jak wcześniej w kolejności alfabetycznej.
