drivers for analog device AD1816A

I am asuming that this is on a sound card.

First, try and identify who made the sound card, and see if you can get the driver from them.

A good resource is www.driverguide.com
They have a good guide to help you identify the card mfg, links tomfg web sites, and if all else fails, theyu have a page of drivers posted by other users.

I haven't looked, but I don't believe that Analog Devices has any reference drivers posted on the web site. This is because the sound chip is only part of the equasion.

If the chip is on your motherboard;
Copy down the bios string that appears near the bottom of the screen during the memory test.
Go to either www.wimsbios.com
or www.motherboards.org
They can help you identify who made your MB. If it is on your MB, I would only trust drivers from the MB mfg.
