make sure the driver you have is correct and on par with your os! some sound drivers are made for a specific os

for this purpose you need to do following :

when you start the computer enter into bios setup.
when you switch on your pc keep on pressing delete button. a menu appers from that go to the motherboard configuration and that menu select audio driver: it must be hd audio deck you should select there realtek audio , now press F10 , press y and then enter. now restart and install the realtek drivers they will be installed without any problem.

1) open device manager click "system devices" disable "microsoft UAA bus driver for high definition audio"
2)uninstall "UAA bus driver" make rescan devices (Note: Not all had this step. You may want to skip it.)
3) install realtek driver the realtek driver includes the UAA driver too.
