How do you update 'RTKVHD64.sys' drivers?

[StuStix]

Hi there,

I just read the sticky thread about getting BioShock's sound to work, and have updated my drivers. However, when I look at my DxDiag.txt, it says I have "RTKVHD64.sys" as my driver. As you can imagine, I'm having a bit of difficulty updating it. I'm reasonably sure it's a RealTek.
