💖 oss_cs461x — bestie edition 💖

okay so real talk, this is page oss_cs461x(7) from the OSS Devices section of the manual, and it's all about one very specific little audio driver. if you're here, you either have some vintage Cirrus Logic silicon in your machine or you're just nosy. either way, welcome, pull up a chair 🫶

✨ NAME ✨

oss_cs461x — the Cirrus Logic CS461x/CS4280 audio driver, no cap.

🌸 DESCRIPTION 🌸

So. This is the Open Sound System driver for the Crystal Semiconductor (Cirrus Logic) CS4280 and 461x audio controllers. yes, Crystal Semiconductor got gobbled up by Cirrus Logic, it's giving corporate merger energy, we move 💅

Now let's talk about what the CS4280 device is actually bringing to the table. its characteristics, if you will:

  • 8/16 bit playback/record 🎧
  • mono/stereo playback/recording 🎀
  • sample rate all the way from 8KHz to 48Khz — that's the range, that's the vibe

that's it, that's the whole feature list, and honestly? it ate. it did what it needed to do. periodt.

✨ OPTIONS ✨

  • cs461x_clk_run_fix=0|1 — lowkey a relic ngl. this feature is not used any longer (their words, not mine, the manpage literally spells it "anylonger" and I am not about to edit the ancestors). back in the day though? certain IBM Thinkpads needed the CLK_RUN bit flipped just to wake the audio device up. iconic behavior from a laptop, honestly. so if you set this, you're either on ancient hardware or you're just being thorough 🌈

🦋 FILES 🦋

  • /etc/oss4/conf/oss_cs461x.conf — the device configuration file. this is where the config lives, that's the whole job 🎀

heads up bestie: if you came here looking for a mountain of flags, this page is not that. one option, one file, one driver. sometimes the quiet ones are the most trustworthy 💜

and that's a wrap!! this page was brought to you by OSS Devices, dated 11 February 2015, and yeah the footer says oss_cs461x(7) again because manuals love to repeat themselves. bye bye, go listen to something at 48KHz for me 🎧✨💖
