SYMPTOMS
After you install a communication and network riser (CNR) SoundMAX audio extension card, Windows XP does not recognize the card. Device Manager lists the card as an unknown PCI device.



CAUSE
This behavior can occur because Windows XP does not support the CNR-based SoundMAX audio extension card.



RESOLUTION
To resolve this behavior, contact Analog Devices, Inc. (ADI) to ask about availability of an updated driver that is compatible with Windows XP. Visit the ADI Web site at:

MORE INFORMATION
The CNR-based SoundMAX (S/PDIF & Optical Output) audio extension card extends audio functionality. Although you can add the card to an i815-based motherboard if the motherboard has a CNR slot, you cannot use the output from the card.

S/PDIF stands for Sony/Philips-Digital Interface.
