9 * Changelog:
10 * Support interrupts per period.
11 * Removed noise from Center/LFE channel when in Analog mode.
12 * Rename and remove mixer controls.
13 * 0.0.6
14 * Use separate card based DMA buffer for periods table list.
15 * 0.0.7
16 * Change remove and rename ctrls into lists.
17 * 0.0.8

24 * 0.0.11
25 * Add Model name recognition.
26 * 0.0.12
27 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
28 * Remove redundent "voice" handling.
29 * 0.0.13
30 * Single trigger call for multi channels.
31 * 0.0.14
32 * Set limits based on what the sound card hardware can do.

34 * capture hw constraints require period_size = n * 64 bytes.
35 * playback hw constraints require period_size = n * 64 bytes.
36 * 0.0.15
37 * Separated ca0106.c into separate functional .c files.
38 * 0.0.16
39 * Modified Copyright message.
40 * 0.0.17
41 * Implement Mic and Line in Capture.
42 * 0.0.18
43 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
