|Most OEM computers have a folder called "drivers" that contain the hardware drivers for the machine. It should be listed when you click on the "C" drive. (My Computer then C) If you have that folder, there should also be a sound folder inside the drivers folder. If it exists, you may also have a setup file that will install the driver for you.|
If not, respond with your computer make / model so we can point you in the right direction.
