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

Audigy-LS device characteristics:

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

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.

OPTIONS

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.
