This is the wiki page about Creative Labs Audigy LS alsa driver. It's called snd-ca0106 - formerly known as snd-audigyls.

Important: Audigy LS cards do not work with the EMU10K1-driver!

Below information is taken from James Courtier-Dutton's comments in the driver sources.

Supported cards

1. SB Audigy LS
2. SB Live 24bit - capture from analog inputs already works fine

FEATURES currently supported

• Front, Rear and Center/LFE.
• Surround40 and Surround51.
• Capture from MIC an LINE IN input.
• SPDIF digital playback of PCM stereo and AC3/DTS works.
• (One can use a standard mono mini-jack to one RCA plugs cable.
• or one can use a standard stereo mini-jack to two RCA plugs cable.
• Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
• ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
• Notes on how to capture sound:
• The AC97 is used in the PLAYBACK direction.
• The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
• So, to record from the MIC, set the MIC Playback volume to max,
• unmute the MIC and turn up the MASTER Playback volume.
• So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
• The only playback controls that currently do anything are: -
• Analog Front
• Analog Rear
• Analog Center/LFE
• Analog Side ( controls the side speakers when adressing them directely through hw:0,3 )
• SPDIF Front
• SPDIF Rear
• SPDIF Center/LFE
• SPDIF Unknown ( couldn't test it but i assume this does the same as analog side for digital. )

• For capture from Mic in or Line in.
• Digital/Analog ( switch must be in Analog mode for CAPTURE. )

• CAPTURE feedback into PLAYBACK

• To capture sound with the SB Live 24bit analog input you must set the "Digital source" control to "i2s in".
