Identifying A Sound Card

Most likely, you have some form of an AC97 codec based sound system.

You need to identify the motherboard and / or system manufacture and model.

Watch the monitor closely at boot.
Near the lower left corner will be the BIOS ID string.
Copy this down and use the tools at either:
www.motherboards.org
www.wimsbios.com
To identify the motherboard.

Another option is to use BIOS Agent from Unicore software.

Since this has on-board sound, have you looked through the BIOS setup screens?
They just might let you know which sound system is on the board.

If you have lived a good life, you may be able to identify the driver needed by taking a close look at the motherboard itself.

Look at the ICs (black rectangles) near the sound ports.
You are looking for a name on the IC such as VIA, Creative, ESS
If you have one of these chips, the manufactures web site should be able to link you to a driver download.

No sound IC?
That just means that the sound processor is built into the chip-set.
Look at the larger ICs on the motherboard.
The 2 ICs that are nearly as large as the CPU are the chip-set.
Common manufactures include:
Intel, AMD, SiS, VIA.
Most of them have an audio driver you can download.

Good luck.

Good answer Chas.

One thing that may help. It is difficult to read and copy BIOS ID string on newer computers since it flashes by rather quickly.

When BIOS ID string appears, press Scroll Lock key. Screen will freeze until you press Enter.
