arcofi -- Siemens PSB2160 audio codec
arcofi* at dio? audio* at audiobus?
The arcofi driver supports the HP ``Audio1'' audio devices, based upon the Siemens PSB2160 ``ARCOFI'' codec, to implement the audio device interface described in audio(4). This device is found onboard HP 9000 workstations models 425e, 705 and 710. The arcofi is limited to a phone-quality mono, 8000 Hz sound. AUDIOCTL SETTINGS The following encodings are supported: AUDIO_ENCODING_ULAW AUDIO_ENCODING_ALAW AUDIO_ENCODING_SLINEAR_BE Natively supported. AUDIO_ENCODING_SLINEAR AUDIO_ENCODING_SLINEAR_LE AUDIO_ENCODING_ULINEAR_LE AUDIO_ENCODING_ULINEAR_BE Software converted to AUDIO_ENCODING_SLINEAR_BE encoding. MIXERCTL SETTINGS The arcofi has three audio ports: inputs.line The `line in' jack connector. outputs.line The `line out' jack connector. outputs.speaker The built-in speaker. Each port has a volume control, and can be muted. The outputs.line and outputs.speaker volume settings are tied to the same hardware setting.
