Driver or hardware

[Ademil4vic]

My laptop dell d520 was formatted with win xp and as usual lost some drivers include sound driver and i drive it and installed this driver,but the system will not play music and at the down left corner of the system there is no speaker icon.so,is it this driver that is not compatible or what? and if it this driver how do i disable it?
    many thanks
