SND_CSA(4)

📦 version 15.1, in freebsd 14.5, freebsd 15.1, nixpkgs unstable

💖 NAME 💖

okay so welcome to snd_csa(4), a Kernel Interfaces Manual page, bestie. the name is literally: snd_csa — Crystal Semiconductor CS461x/462x/4280 PCI bridge device driver. that's the whole vibe, no cap 💅.

✨ SYNOPSIS ✨

if you wanna compile this driver into the kernel, drop these lines into your kernel configuration file, fr fr:

device sound
device snd_csa

or, if you're more of a load-it-as-a-module-at-boot-time girlie, put this line in loader.conf(5):

snd_csa_load="YES"

slay either way 🫶.

🎀 DESCRIPTION 🎀

so what does it actually do? the snd_csa bridge driver lets the generic audio driver sound(4) attach to Crystal Semiconductor CS461x/462x/4280 based sound cards. it's giving matchmaker energy, but for your audio stack 😭💖.

🦋 HARDWARE 🦋

the snd_csa driver supports these sound cards, and yes we're listing every single one because details are cute:

  • Crystal Semiconductor CS4280
  • Crystal Semiconductor CS4610
  • Crystal Semiconductor CS4611
  • Crystal Semiconductor CS4614
  • Crystal Semiconductor CS4615
  • Crystal Semiconductor CS4622
  • Crystal Semiconductor CS4624
  • Crystal Semiconductor CS4630
  • Genius Soundmaker 128 Value
  • Hercules Game Theatre XP
  • Turtle Beach Santa Cruz
ngl there's a little plot twist: some onboard CS4610 chips are accompanied by the CS423x ISA codec instead of the CS4297 AC97 codec. Such configurations are not supported by the snd_csa driver yet 😭. so close but no cigar, bestie.

🌸 SEE ALSO 🌸

  • sound(4) — that's the one. go read it, iykyk 💜.

⭐ HISTORY ⭐

The snd_csa device driver first appeared in FreeBSD 4.0. iconic behavior, honestly 👑.
