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
18  *    Try to fix capture sources.
19  *  0.0.9
20  *    Fix AC3 output.
21  *    Enable S32_LE format support.
22  *  0.0.10
23  *    Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
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.
33  *    playback periods_min=2, periods_max=8
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)
