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.
The "recmon" button enables a passthrough of the analog input signal.
Monitor Volume slider sets the passthrough gain if recmon is enabled.

OPTIONS
