I have a Razer Studio Edition and am wanting to take advantage of HD Audio.  My device manager shows two devices.  Realteck Audio (Not HD) and Nvidia High Definition Audio.  After much google searching I couldn’t find a solution.  Nvidia device shows not plugged in and I can’t seem to figure out how to enable it.  If I do enable it will it actually work? Because right now it is using the Realteck driver.  Is Realteck the only option?  If not, is there a way to enable Nvidia HD Audio so I can take advantage of advanced features to tweak my audio settings.
