Sound Problem

Hey, so I just had an ATI HD4850 installed in my computer, and it made the sound go all wonky for a bit. So, eventually I found the problem, which was conflicting drivers. An ATI sound driver was installed, and the old driver from Realtek HD Audio was still there, so I uninstalled that, and now the sound works again. But, my problem is, the sound is really flat, like there's no equalizer or something. Before I installed it, I had this nice little option in the bottom right corner that brought up all these different things like "Powerful, Rock, Pop, Jazz, Indie" equalizers, along with settings like "Living room, Sewers, Parking Lot" etc, to give it unique sounds like it was being played somewheres different. Any idea how I get this back?

Edit: Also, when I go into System Information, and into the Sound devices, it tells me I have two installed. ATI Function Driver for High Definition Audio - ATI AA01, and Realtek High Definition Audio.

Edit Edit: Nevermind guys, the guy at the store had installed the wrong drivers, I just had to uninstall them and put the right ones on. Delete this thread if you want.
