You don't want drivers from Microsoft - in most cases these are only generic drivers, not specifically matched to your hardware.
This often leads to problems such as not being able to select the correct input, or recordings not being made correctly.
Then on all versions of Windows, expand "Sound, Video and Game Controllers" by clicking on the sign, right-click over the sound device and click "update driver".
After the update (even if more recent drivers were not found), you should right-click over the device again, click Properties and then on the Driver tab to check the "Driver Provider".
You may need to find out the name, specifications and current driver details for your sound device, so you can update it correctly.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.
