When you run Windows XP on a computer with a sound card that is based on the Aureal 8820 chipset, your computer may stop responding (hang), forcing you to restart the computer. This is most likely to occur when you log on if you have a sound event associated with logging on, or if you right-click on an item to see a context menu and you are using the new Windows XP theme.

NOTE: If the computer does not stop responding, you may hear a short burst of sound, and then lose all sound.
