no sound
 

I just installed the newest version of s2u2 and know i have no sound, so i uninstalled it and still no sound. All the volume sliders are on high and the sound notifications are on loud, i also get no sound on my media player or when the phone rings. I only get great sound when i plug in my headphones.
Any suggestions please help.
