Ali drivers can be had here... there's enough English in there that you should be able to find the right ones without knowing any Chinese. (Download links are over on the right side... the "下载".)
What sort of Vortex 2 card do you have? The generic Aureal drivers can be had from Nodevice... they have both the driver-only packages, and the full software/demo packages. But if you have something like a Diamond or Turtle Beach card, you may be happier with the specific packages put out by the card manufacturer.
And for the PCX2, here's the wacked bush that leileiol was referring to. (BTW, lei, your username is a PITA to type.)
