Beats Audio Driver for 4-1130us ultrabook

Hello,

Recentel installed Win 7 on my notebook.

I seem to have lost the Beats Audio driver and cannot locate it under the drivers...

Can someone please help me?

Also the light above my Mute button (fn F11) does not work either.

thanks in advance

John
