NAME
vidcaudio —
VIDC audio device driver
SYNOPSIS
vidcaudio0 at vidc0
audio* at vidcaudio0
DESCRIPTION
Thevidcaudio driver provides support for the audio
system of the ARM VIDC20 and of the video and sound macrocell of the ARM7500
and ARM7500FE.
The driver can work in two modes, either using the internal 8-bit
DACs of the VIDC20 and its internal reference clock, or using the serial
sound output of any supported chip feeding external 16-bit DACs and an
external sound clock. On systems with a VIDC20, the choice of mode is based
on the ‘*Configure SoundSystem’
setting under RISC OS.

HISTORY
The vidcaudio driver was introduced in
NetBSD 1.2. The driver was largely rewritten for
NetBSD 2.0 because it had bit-rotted so far as to be
useless.
AUTHORS
The first version was written by Melvin Tang-Richardson. The rewrite was by Ben Harris.
