Ok, so I went out and bought that Dynex Gigabit PCI card at Best Buy, and it works without anything needed on my part.

I tested mine sound, and went by how OP told to set it up. The system sound plays sound, but when I go into safari and play a flash video, I don't get any sound at all? Gonna try normal media files and see where that gets me, but I can't figure out the flash video sound issue,

NEVERMIND. I forgot to change the Output tab too. Hehe. It works fine now. This is awesome! Now I just gotta test and see if my DVD drive works, and its all good. I also have to get around to installing Fusion, I wonder how that will work.
