🎀 arcofi(4) — the Siemens PSB2160 audio codec, but make it a vibe 🎀

🦋 NAME 🦋

arcofi — the Siemens PSB2160 audio codec, here to serve phone-quality sound and main-character energy 💅

✨ SYNOPSIS ✨

arcofi* at dio?
audio*  at audiobus?

🌸 DESCRIPTION 🌸

Okay bestie, so the arcofi driver supports the HP “Audio1” audio devices, and those cuties are based upon the Siemens PSB2160 “ARCOFI” codec. It implements the audio device interface described in audio(4) — yes, that whole situation 💖

This device is found onboard HP 9000 workstations models 425e, 705, and 710. Iconic little onboard moment, no cap ✨

The arcofi is limited to phone-quality mono, 8000 Hz sound. It’s giving vintage telephone realness, and honestly? We respect it 🫶

🌈 AUDIOCTL SETTINGS 🌈

The following encodings are supported, bestie — take notes 📝

Natively supported ✨

  • AUDIO_ENCODING_ULAW
  • AUDIO_ENCODING_ALAW
  • AUDIO_ENCODING_SLINEAR_BE

Software converted to AUDIO_ENCODING_SLINEAR_BE encoding 💅

  • AUDIO_ENCODING_SLINEAR
  • AUDIO_ENCODING_SLINEAR_LE
  • AUDIO_ENCODING_ULINEAR_LE
  • AUDIO_ENCODING_ULINEAR_BE

🎧 MIXERCTL SETTINGS 🎧

The arcofi has three audio ports, and they are absolutely doing their thing:

  • 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. Very demure, very mindful 🎀

The outputs.line and outputs.speaker volume settings are tied to the same hardware setting. So yeah, they’re linked — iykyk 💀

🦋 HISTORY 🦋

The arcofi driver was written for OpenBSD and first appeared in OpenBSD 5.1, and was ported to NetBSD. A little cross-system slay, periodt 🌟

💖 Okay that’s the whole page — Debian edition, dated August 25, 2014, and yes bestie, it’s ARCOFI(4). Bye! 💖
