Locate the Audio device properties and see if it has the correct driver. If the driver is missing, locate the CD that came with the system and update the audio driver from there. Alternatively you can get the driver from the manufacture's website

• From the start menu select Control Panel
• Locate the System icon and open it.
• Click the Hardware tab
• Click device manager button to open.

• Select Update Driver.
• You'll be prompted to insert CD.
• Driver will be installed from the XP cd.

You might want to go to the microsoft web site to see if updated drivers are available for your device.

Many times what happens is during Microsoft updates this audio card PC driver gets lost.
You may need to go to Dell's Web site to locate your specific Model's audio card driver and then reload it.
Worth a try!
