Updating sound driver
Your computer manufacturer may have altered the features, incorporated customizations, or made other changes to your driver.
We recommend that you save it to your desktop and initiate the free scan using the desktop icon.
Tip: Updating drivers yourself is not difficult, but there are programs that will more or less do it for you.
See my List of Free Driver Updater Tools for reviews of the best ones out there.
A driver update isn't always a fix-it task, either.
An updated driver might enable new features for the hardware, something I see on a regular basis with popular video cards and sound cards.
