I have read through a few threads on the forums, but am still unsure what cable I need to connect my Gamecube to my system. I am looking for a component (pref) or RGB SCART lead, that will also allow me to output sound to my surround amp. It looks as though the official leads do not have separate sound connections. I have got Ixos leads for my PS2, but they do not make a Gamecube equivalent. What is everyone else using?
