AC-97 chip sets

(Version: page rev. 1.33/ 18.02.2004)

AC-97 is a general term for a certain kind of on-board chip set, i.e. there is no sound card to insert into the computer, but the chip is built onto the motherboard itself instead. Sound quality usually isn't very high for both playing and recording, and some chips are also quite limited in terms of supported sampling rates, etc.

If you don't know which chip you have, see the code which is printed on top of the chip or check the web site of your motherboard's manufacturer. If both methods fail, use the latest version of the PCI hardware sniffer which has been ported by Veit Kannegieser. Search for pci*vk.zip at Hobbes.

Some of the chip set manufacturers, IBM, or freeware developers write drivers for certain chip sets. This results in support for all motherboards which use the specific chip set.
