is the sound card you had intergrated? did you disable it from the bios etc. You can also try resetting that too, you never know. Little things like that sometimes make a world of a diff..
If not, it could be your motherboard, try moving the sound card to another PCI slot and check that the IRQ's aren't getting mixed up.
Are you having problems with any other games on your PC? If not then it might be a problem with FF and you can wait for another POL update (.......) or try the old pol.exe
that's all i can think of right now.
