Realtek released version 3.67 driver for their ALC AC97 audio chipsets. The driver supports all ALC series audio chipsets from ALC100 up to ALC850 mainly used as onboard sound on various motherboards.

The ALC650 incorporates proprietary converter technology to achieve a high SNR, greater than 90 dB. The ALC650 AC'97 CODEC supports multiple CODEC extensions with independent variable sampling rates and built-in 3D effects. The ALC650 CODEC provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs.
