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:

http://downloadfinder.intel.com/scripts-df-external/Support_Intel.aspx

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