Introduction

The Via VT82C686A "super southbridge" chips contain AC97-compatible audio logic which features dual 16-bit stereo PCM sound channels (full duplex), plus a third PCM channel intended for use in hardware-assisted FM synthesis. The VIA VT8233/8235 extends this support to include six channel output and additional record facilities.

The current Linux kernel audio driver for this family of chips supports audio playback and recording, but hardware-assisted FM features, and hardware buffer direct-access (mmap) support are not yet available.

This driver supports any Linux kernel version after 2.4.10.
