The audioce
device uses the Crystal
Semiconductor CS4231A Parallel Interface, Multimedia Audio Codec chip to
implement the audio device interface described in
audio(4). This device is found
onboard on some PCI/EBus based sparc64 models.
The audioce
has a maximum precision of 16
bits and has both stereo and monoaural outputs.
The audio(4)
interface for audioce
provides the following
controls:
outputs.dac

’ represents 0 dB
attenuation.outputs.dac.mute
outputs.output
line
’, the line output jack,
‘hp
’, the low impedance headphone
jack, and ‘spkr
’, the internal
speaker. Note: Not all systems support disabling the headphone and line
output ports.inputs.cd

heard on the output ports.record.mic_preamp
OpenBSD support for
audioce
first appeared in OpenBSD
