Multimedia audio controller

This indicates that the sound drivers are missing from your computer. You will have to identify the sound card that is installed on your computer before proceeding with downloading the correct driver. To identify the sound card, follow the steps below (Assuming that you are using Windows XP)

1. Open Device Manager (Right-click My Computer>Properties>Hardware>Device Manager)
2. The hardware whose drivers are missing will appear as Unknown device, so it’s easier to locate the device.
3. Right click on the unknown device and click on Properties.
4. Under the Properties window click on Details tab and select Device Instance Id from the drop down box.
5. You should see a code similar to this
   PCI\VEN_8086&DEV_27DC&SUBSYS_30868086&REV_01\4&1E46F438&0&40F0
6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:
   Vendor ID = 8086
   Device ID = 27DC
7. Once you have obtained both the IDs, proceed to www.pcidatabase.com . There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.
