Locating Drivers

If you need help locating where to get the latest drivers for your sound card try the following.  Your Device Manager in Windows should supply the information assuming the sound card has been detected.  To access the Device Manager right click on My Computer and select the Device Manager tab.  In Windows XP go to the Hardware Tab and select Device Manager.

If you don’t know how to access the Device Manager or it doesn’t show your card, than the easiest thing to do is download a free utility like Belarc Advisor.  Run the installer then it will open a webpage for you.  Under Multimedia it will tell you the sound card or Audio Controller you have in your PC.  You may now go to that company’s website and download the drivers and reinstall them.
