SYMPTOMS
On a Dell Latitude CPx portable computer that has an ESS Maestro 2E audio device, there may not be any sound when the computer is in its docking station.

When you check the volume control, the master volume control slider may be set to zero (0). When you set the volume control, the master volume control slider gradually slides back down to zero. When a sound does play (for example, a bell, a media file, or an audio CD), the master volume returns to the value that you set but then gradually slides back down to zero again.



CAUSE
This behavior can occur because of a problem with the ESS Maestro 2E audio device drivers that are shipped with Windows 2000.



RESOLUTION
To resolve this behavior, contact Dell to obtain an updated audio device driver, and then install the updated driver on your computer.
