Do you mean how do you locate the driver for a sound card? 

Instructions
1
Look for a disk accompanying the sound card. In a new computer, this may be included with a bundle of other driver disks. A new sound card usually has a driver CD-ROM included in the package with the hardware.

2
Check online at the manufacturer's website for a downloadable copy of the sound card driver. Downloadable drivers are usually located in the "Downloads" or "Support" section of most manufacturer websites.

3
Visit the website of the company that manufactured your computer for special sound drivers for your specific system.

4
Call, email or write a letter to the sound card or computer manufacturing company to request replacement disks. Most manufacturers list a telephone number on the product package and again on their website.
