AUDIOCE(4)	     OpenBSD Programmer's Manual (SPARC64)	    AUDIOCE(4)

     audioce - SPARC64 EBus CS4231 audio device

     audioce* at ebus?
     audio* at audioce?

     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 mixer(4) interface for audioce provides the following controls:

     outputs.dac	   Specifies the attenuation of DAC output.  A value
			   of `255' represents 0 dB attenuation.

     outputs.dac.mute	   Specifies whether DAC output is muted.

     outputs.output	   Specifies the set of enabled output ports.  The
			   output ports are: `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.		   Specifies the gain applied to CD audio input.  A
			   value of `191' represents 0 dB.	   Specifies whether CD audio input is muted.

     inputs.line	   Specifies the gain applied to line input.  A value
			   of `191' represents 0 dB.

     inputs.line.mute	   Specifies whether line input is muted.

     outputs.monitor	   Specifies the attenuation of ADC to DAC output.  A
			   value of `255' represents 0 dB.

     outputs.monitor.mute  Specifies whether ADC to DAC output is muted.

     record.volume	   Specifies ADC input gain.  A value of `0'
			   represents 0 dB.

     record.source	   Specifies the active input port for the ADC.	 The
			   following are valid ADC input ports: `line', line
			   input, `cd', CD input, `mic', microphone input, and
			   `mixerout', post-mixer output as heard on the
			   output ports.

     record.mic_preamp	   Specifies whether an additional +20 dB gain is
			   applied to the ADC's microphone input.

     OpenBSD support for audioce first appeared in OpenBSD 3.0.
