* Version: 0.0.18
*
* FEATURES currently supported:
* See ca0106_main.c for features.
*
* Changelog:
* Support interrupts per period.
* Removed noise from Center/LFE channel when in Analog mode.
* Rename and remove mixer controls.
* 0.0.6
* Use separate card based DMA buffer for periods table list.
* 0.0.7
* Change remove and rename ctrls into lists.
* 0.0.8
* Try to fix capture sources.
* 0.0.9
* Fix AC3 output.
* Enable S32_LE format support.
* 0.0.10
* Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
* 0.0.11
* Add Model name recognition.
* 0.0.12
* Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
* Remove redundent "voice" handling.
* 0.0.13
* Single trigger call for multi channels.
* 0.0.14
* Set limits based on what the sound card hardware can do.
* playback periods_min=2, periods_max=8
* capture hw constraints require period_size = n * 64 bytes.
* playback hw constraints require period_size = n * 64 bytes.
* 0.0.15
* Separated ca0106.c into separate functional .c files.
* 0.0.16
* Modified Copyright message.
* 0.0.17
* Implement Mic and Line in Capture.
* 0.0.18
* Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
