Updating navigation system
"Icons" views have a direct link to Device Manager, as does "Classic View" on Windows Vista only.
Windows XP and earlier: Click , click on the Hardware tab, then on the "Device Manager" button on the Device Manager panel.
If an update has occurred at any time, the button will be active.
You can click this button to revert the driver to its previous installation.
Manufacturers of motherboard sound devices such as Realtek, Sigmatel and Soundmax do not usually provide any driver support to end users.
Windows Update is potentially less reliable about obtaining appropriate hardware updates than Windows Device Manager.
If you suspect a driver update problem, launch Device Manager from the Windows Control Panel.
To do this, you can use Device Manager on Windows, System Profiler on a Mac or the /lspci or /lsusb commands on Linux.
Device Manager can also try and update the drivers for you itself, and Windows users are strongly recommended to try this update facility as a first step - see Extra help for Windows users below.This is easiest, but may not necessarily find the latest or most appropriate drivers.
