SND_CSA(4)

💖 SND_CSA — Crystal Semiconductor CS461x/462x/4280 PCI bridge device driver 💖

okay bestie, welcome to the snd_csa(4) page, aka the Kernel Interfaces Manual entry for the Crystal Semiconductor CS461x/462x/4280 PCI bridge device driver. yes the name is long. no we are not shortening it. it's giving ✨legacy audio✨ and honestly? we respect it.

🌸 SYNOPSIS 🌸

so there's two ways to get this driver living in your life, and it depends on the vibe:

Option one — bake it right into the kernel. put these lines in your kernel configuration file:

device sound
device snd_csa

Option two — load it as a module at boot time. drop this line into loader.conf(5):

snd_csa_load="YES"

pick your fighter. both work. 💅

🎀 DESCRIPTION 🎀

the snd_csa bridge driver is basically the wingman here — it lets the generic audio driver sound(4) attach to Crystal Semiconductor CS461x/462x/4280 based sound cards. that's it, that's the job. the way it just... bridges. iconic behaviour fr fr. 🫶

🔥 HARDWARE 🔥

here's the full roster of sound cards this driver supports, no gatekeeping:

• 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

🚨 okay important caveat, do NOT skip this: some onboard CS4610 chips come with the CS423x ISA codec instead of the CS4297 AC97 codec. those particular configs are not supported by the snd_csa driver yet. so if yours is one of those, it's giving unsupported, and we're all sad about it. 😭

⭐ HISTORY ⭐

the snd_csa device driver first appeared in FreeBSD 4.0. vintage. a classic. an elder that ate. 👑
