I tried two optical digital converter and these doesn't work. Maybe my ps2's optical output is broken.
Finally I bought an HDMI audio converter and it totally works.
I play Okami. It's good. My first PS2 game.
And I also can play PS1 games. I played "Um Jammer Lammy" yesterday. I think that is the best game in PS1.
