💖 oss_ich — the manual page, but make it cute 💖

okay so bestie, you're reading the oss_ich page from section 7 of the OSS Devices manual, and honestly? it's a whole vibe. let's get into it ✨

🌸 NAME 🌸

oss_ich — the Intel ICH / SiS7012 / Nvidia / AMD audio device driver. yes she does all four, she's versatile like that 💅

🦋 DESCRIPTION 🦋

so basically it's the Open Sound System driver for Intel ICH, nVidia Nforce, AMD and SiS 7012 devices. that's it, that's the girl. she just runs your audio. iconic behavior, no notes 🔥

✨ OPTIONS ✨

here's where the fun stuff lives. three options, all of them tuning knobs, all of them real. read carefully bestie, these are literally the whole personality of this page:

  • intelpci_rate_tuning=<NNN> — default is 240. okay so listen: some Compaq Deskpro models (EN and EX at least) and certain Dell models play and record audio at a higher speed than what's expected. rude of them honestly. so if you've got an Intel815 motherboard with an AD1885, you can try setting this parameter to 240, 280 or 330 and see which one works for your system. and the way you figure out the right value?? you use the osstest application. it reports a sample rate drift value — it's called "Sample rate drift" or "srate drift". then you plug that number into this formula and round the result to the nearest integer:
intelpci_rate_tuning = (240*(drift+100))/100

that's it. math girl summer 🧮✨

  • intelpci_force_mmio=<0|1> — default is 0=Disable. this one lets you force the ICH4/ICH5 and ICH6 controllers to run in memory mapped mode so you can free up I/O address space. like a lil spring cleaning for your address space 🧹🫶
  • ich_jacksense=<0|1> — default is 0. this forces the use of jacksensing on some AD198x mixers. jack sense said "let me in" and this option says "okay fine" 🙈

🎀 FILES 🎀

  • /etc/oss4/conf/oss_ich.conf — the device configuration file. that's where she keeps her settings, in her little conf home 🏠💜

👑 AUTHOR 👑

4Front Technologies — the legends behind this whole thing. bow down, they ate 💅

ok that's the whole page bestie, you're officially an oss_ich expert now. no cap. 🌈⭐

and that's a wrap on the oss_ich(7) page from the OSS Devices manual — this lil drop is dated 11 February 2015 💖 bye bye, go make some beautiful audio 🎀🦋
