How to Update Audio Drivers ?

Drivertuner is the final solution to audio drivers problems. This update was released to improve compatibility with newer hardware that contains the Realtek audio chipset. Because you’re likely to gain much by updating, I do recommend you install Drivertuner since it is based on manufacturer’s website.

Method 1:
To update the sound card driver, follow these steps:
Click Start, click Control Panel, and then double-click System.
Click the Hardware tab, and then click Device Manager.
If you are prompted for an administrator password or for confirmation, type the password, or click Continue.
Click Sound, video, and game controllers to expand.
Under Sound, video, and game controllers, double-click the entry for your sound card, and then click the Driver tab.

Note If a Driver tab is not present, the entry that you clicked under Sound, video, and game controllers may not be the correct entry for your sound card. Try clicking any additional entries listed under Sound, video, and game controllers.
Click Update Driver Software.
Follow the Update Driver Software Wizard to update the sound card driver.
