* Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
- * Version: 0.0.20
+ * Version: 0.0.21
*
* FEATURES currently supported:
* See ca0106_main.c for features.
* Added I2C and SPI registers. Filled in interrupt enable.
* 0.0.20
* Added GPIO info for SB Live 24bit.
+ * 0.0.21
+ * Implement support for Line-in capture on SB Live 24bit.
*
*
* This code was initally based on code from ALSA's emu10k1x.c which is:
* bit 9 0 = Mute / 1 = Analog out.
* bit 10 0 = Line-in / 1 = Mic-in.
* bit 11 0 = ? / 1 = ?
- * bit 12 0 = ? / 1 = ?
+ * bit 12 0 = 48 Khz / 1 = 96 Khz Analog out on SB Live 24bit.
* bit 13 0 = ? / 1 = ?
* bit 14 0 = Mute / 1 = Analog out
* bit 15 0 = ? / 1 = ?
