I realised that even though some games supported it, e.g. RE4, my 5.1 speakers are not outputting the surround sound. Even games on the snes9x or zsnes does give me surround sound, provided the games supported it.
I'm no expert, but no Creative card can decode DPL (in hardware), as far as i know... although i certainly wish it could be done, since i've been craving for a way to do this and enjoy DPL in many Gamecube games (played through real hardware, in this case).Hoho....Squall-Leonhart, you are like a walking emulation encyclopedia.
Base on your post, does it mean the 'limitation' on my end, at least, is my onboard sound & OS? You mentioned windows x64, do you mean i'll get a better chance using windows XP/7 x86? Would a creative x-fi card help, too?
