update Ive done this but it always says latest driver already installed..
before i re installed vista on my PC i use to have realtek but i never redownloaded it ?
The Realtek driver controls your sound card in your desktop or laptop computer.
Because technology advances so quickly, errors with audio can occur even when your driver appears to be functioning properly.
Choose the "Save As" or "Save to File" option instead of the "Run" option.
This brings up the window to tell you what the make and model of your sound card is. You can choose to download from the Realtek website or another website of your choice.
If above two methods don’t work for you, or if you don’t have patience, time or computer skills to update the driver manually, you can do it automatically with Driver Easy.
Driver Easy will scan your computer to detect any problem drivers in your computer.
Click "Start" on your computer's desktop task bar, then click "All Programs" and then choose "Accessories" from the menu.
Select "System Tools" from the drop down menu and scroll down to "System Information." On the side menu, click "System Information." You will then get a screen that gives you another menu and a window with your system summary information.
