VIDCAUDIO(4)        NetBSD/acorn32 Kernel Interfaces Manual       VIDCAUDIO(4)


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

     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.
