oss_audigyls(7) Creative Labs CA106 (AudigyLS/SBLive 24bit) driver.


Open Sound System driver for Creative Labs Audigy2-LS and SBLive 24bit 7.1 soundcards.

Audigy-LS device characteristics:

  • 8/16/24 bit playback/record
  • mono/stereo/4/5.1 playback
  • 8KHz to 192Khz sample rate.


There are 2 models of the AudigyLS device: one with an AC97 codec called the AudigyLS and the one without called the SBLive 7.1. Essentially they are the same chip but behave a bit differently.

When playing AC3 on the AudigyLS (the one with the AC97 mixer) - you need to ensure that the igain slider is set to 0.


  • The AudigyLS has 4 mixer controls for each channel.
  • The "spread" button will simply duplicate the front audio on the other 3 channels so that every speaker is playing what the front L/R is playing.
  • LoopBack recording allows you to capture any channel that's playing audio.
  • Record Volume slider just adjusts the input gain.
  • Record Source selector selects the input.
  • The "recmon" button enables a passthrough of the analog input signal.
  • Monitor Volume slider sets the passthrough gain if recmon is enabled.


  • audigyls_spdif_enable=0|1 The Audigy LS has a versa-jack (orange) that can be set as SPDIF output or the Side-Surround left/right speakers in a 7.1 setup. When set as SPDIF, you can get play PCM/AC3 audio to a Dolby(R) capable receiver.
