I found this on the PB site, I don't know if it could help: > Description > The ALC260 2-Channel High Definition Audio Codec with UAA (Universal > Audio Architecture) is designed for commercial desktop and notebook PC > systems and features a 24-bit two-channel DAC and two stereo 20-bit > ADCs. The codec incorporates proprietary converter technology to > achieve 95dB sound quality; easily meeting PC2001 requirements and > also bringing PC sound quality closer to consumer electronic devices. > > The ALC260 provides two output channels, along with flexible mixing, > mute, and fine gain control functions to provide a complete integrated > audio solution for PCs. The DAC (with a highest sampling rate of 192 > kHz) and Realtek proprietary hardware content protection are > applicable for DVD-Audio; previously only implemented in high-end > consumer electronics but now achieved by PCs equipped with the ALC260. > The ALC260 provides high-quality audio using S/PDIF to output analogue > data, or for multiple-source recording applications. > > Realtek's proprietary impedance sensing and jack detect techniques > allow device loads on inputs and outputs to be auto-detected. All > analogue IOs are input and output capable. Headphone amplifiers are > also integrated at each analogue output. All analogue IOs can be > re-tasked according to user's definitions, or automatically switched > to suit the connecting device (Universal Audio Jack). > > The ALC260 supports 32-bit S/PDIF input and output functions, with a > sampling rate of up to 96 kHz, offering easy connection of PCs to high > quality consumer electronic products such as AC-3 decoders/speakers, > and mini disk devices. > > The ALC260 supports host/soft audio from the Intel ICH6 chipset, as > well as from any other HDA compatible audio controller.
