* Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
- * Version: 0.0.21
+ * Version: 0.0.22
*
* FEATURES currently supported:
* See ca0106_main.c for features.
* Added GPIO info for SB Live 24bit.
* 0.0.21
* Implement support for Line-in capture on SB Live 24bit.
+ * 0.0.22
+ * Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
*
