NAME
oss_audigyls - Creative Labs CA106 (AudigyLS/SBLive 24bit) driver.
DESCRIPTION
Open Sound System driver for Creative Labs Audigy2-LS and SBLive 24bit 7.1
soundcards.
Audigy-LS device characteristics:
o 8/16/24 bit playback/record
o mono/stereo/4/5.1 playback
o 8KHz to 192Khz sample rate.
AUDIGYLS MODELS
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.
AUDIGYLS MIXER
o The AudigyLS has 4 mixer controls for each channel.
o 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.
o LoopBack recording allows you to capture any channel that's playing audio.
o Record Volume slider just adjusts the input gain.
o Record Source selector selects the input.
o The "recmon" button enables a passthrough of the analog input signal.
o Monitor Volume slider sets the passthrough gain if recmon is enabled.
OPTIONS
o 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.
