Overview

The snd_csa bridge driver allows the generic audio driver sound(4) to attach to Crystal Semiconductor CS461x/462x/4280 based sound cards.

Hardware

The snd_csa driver supports the following sound cards:

  • 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

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.
