I checked synaptics and it seemed that all but libao4 was installed. I installed libao4 and when i restarted the sound icon had disapeared from the task bar at the bottom of my desktop. I tick and untick the sound icon from the panel settings but it doesnt come back. I go to sound settings and its all grayed out.
