AC97 Sound solutions
| What is AC97 Sound? | |||
| The AC97 Specification provides a way of providing a low cost, high quality sound solution to board manufactures. | |||
|
This is done by embedding half of the required technology in the motherboard chipset (South Bridge) and the other half is a separate chip from an OEM supplier. As the solution is fitted/provided in two locations, it sometimes must be disabled in two locations should you wish to add another PCI sound card. |
|||
| The Embedded part of the solution (Southbridge) provides the Sound output and can normally be enabled/disabled in the BIOS. | |||
| The Additional Chip (Such as the AD1881) provides the effects (such as reverb) to the sound signal and sometimes has to be enabled / disabled by a link on the motherboard. Some Chips such as the Analogue Devices AD1885 also offer advanced features such as surround sound. | |||
|
Please be aware that the AC97 Specification also includes provision for
Modem and LAN technology built within the chipset. 1) If an AC97 Modem/LAN card is used in conjunction with an AC97 Sound solution, then use the links on the Modem / LAN card to set the card as the Slave device (Sound must be master by default). 2) If you disable the AC97 Sound solution (by BIOS & sometimes link on the MB), then you need to promote the modem/LAN to be Master (by links on the Modem/LAN card) . You cannot have a Slave device without a master. |
