Sounds Bad with realtek HD audio Driver !!

Hey,
I am using Realtek Audio driver in my system cause i want stereo mix does anyone know how to change speakers and headphones drivers to Windows HD audio driver, But still i want stero mix driver

The Windows High Definition Audio driver is a generic, basic function, sound driver. It does not contain all the "bells and whistles".

What is "bad" about the Realtek audio? Its used in millions of PC's and works fine. I have Realtek on all of my PC's (two desktops and a laptop) and do not have "bad" sound with it.

Also, please fill in the "My System Specs" so we know what you have. It helps use to try and help you.
