How to update sound card drivers?

[ComputerGod91]

Apparently it isn't as easy as it sounds, I can't figure it out. I have Realtek HD audio sound card and I have no idea where to go to download the latest drivers and be sure that they are the latest. Can someone point me in the right direction?

Im using Windows 7 64bit
