Hi Jeff,

Here are three ways to install a driver:

• Use Windows Update. You might need to set Windows Update to automatically download and install recommended updates. Installing any important, recommended, and optional updates can update system features and other software that might help fix your sound problems.
• Install software from the device manufacturer. If your device came with a disc, that disc might contain software that installs a driver for the device.
• Download and install the driver yourself. You can search for a driver on the manufacturer's website. Try this if Windows Update can't find a driver for your device and the device didn't come with software that installs a driver.

To update the driver using Windows Update

1. Open Windows Update by clicking the Start button . In the search box, type Update, and then, in the list of results, clickWindows Update.
2. Click Check for updates.If there are any available updates, click the links to see more information about each update. Windows Update tells you if an update is important, recommended, or optional. Each type of update might include drivers.
3. On the Select the updates you want to install page, look for updates for your sound card, select the check box for the driver that you want to install, and then click OK.
   There might not be any available driver updates.
4. On the Windows Update page, click Install updates. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
   

   Windows Update will tell you if the updates were successfully installed.

To download and install a driver yourself

If Windows can't find a driver for your sound card or sound processor, and the device didn't come with driver software, you can look for a driver on the manufacturer's website. Driver updates are often available in the support section of such websites.
To locate the driver, find the manufacturer and model name or number of your sound card, and then visit the Hardware and software vendor contact information website.
Once you find your manufacturer, go to its website and locate and download the latest driver for your sound card.
If there's an updated driver, follow the installation instructions on the website.
Most drivers are self-installing—after you download them, you usually double-click the file to begin the installation, and then the driver installs itself on your computer.

I hope this helps.

Lokesh.
