My sound on my computer does not work!!!

check your sound plug and make sure that the wires are working, if that not the case see if it's your sound driver, to find out that the problem is with the  sound driver go to device manager , if it shows a question mark(?) just click on " update driver ". if that doesn't work u going to have to go to your manufacture website and download the driver directly. just look under computer for a product number and enter it on the manufacture's website. if your using a desktop the manufacture number is on the side =)
