The Realtek ALC655 Sound is an audio codec chip that was widely used in desktop computers and motherboards during the early 2000s. It supported 6-channel audio, delivering a basic surround sound experience for multimedia and gaming applications. Following the AC'97 audio standard, it integrated audio functions into motherboard chipsets, reducing costs and simplifying audio implementation. While the ALC655 served its purpose during its era, it is now considered outdated by modern standards. Today's audio solutions offer higher quality, greater versatility, and improved driver support, making them more suitable for the demanding audio needs of contemporary computing and entertainment systems.
