The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Professional
This article was previously published under Q297386

SYMPTOMS

Changing the master volume level for an ADI AD1885 sound device does not control the volume for headphones that are connected to the device.

CAUSE

This behavior occurs because the ADI AD1885 sound device has a separate amplifier for the headphone output. The default driver for this device that is installed with Windows 2000 controls only the main output amplifier when you adjust the volume.

RESOLUTION

This sound device is installed by a number of Original Equipment Manufacturers (OEMs). To resolve this issue, obtain an updated driver from your OEM.

MORE INFORMATION

The ADI AD1885 sound device is detected by Windows 2000 only after the Intel ICH2 driver has been installed. The driver is available for downloading from the following Intel Web site:

The updated driver that is supplied by Intel is also available at this location.
