NAME
vidcaudio
- VIDC audio device driver
SYNOPSIS
vidcaudio0 at vidc0
audio* at vidcaudio0
DESCRIPTION
The
vidcaudio
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

vidcaudio
driver was introduced in

The driver was largely rewritten for
NetBSD2.0
because it had bit-rotted so far as to be useless.
