nie ma dla mnie znaczenia, ze sb obsluguje tylko 4 glosniki, i tak jest podpiety przez s/pdif wiec dekodowaniem do 5.1 zajmuje sie zewnetrzny dekoder. EAX dzialaj tylko na 4 glosnikach -analog (jesli sie nie myle) wiec dodatkowe wyjscie (center/sub) do gier nie jest potrzebne i tu sb sprawdza sie. Pytanie, czy warto kozystac z eax 2.0 na zintegrowanej karcie(software?) zamiast na sb z eax 1.0 (sprzetowe wspomaganie). Przetworniki analogowe sa chyba lepszej jakosci na sb, ale co z reszta?
