   3  *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
   4  *  Version: 0.0.21
   5  *
   6  *  FEATURES currently supported:
   7  *    Front, Rear and Center/LFE.
   8  *    Surround40 and Surround51.
   9  *    Capture from MIC an LINE IN input.
  10  *    SPDIF digital playback of PCM stereo and AC3/DTS works.
  11  *    (One can use a standard mono mini-jack to one RCA plugs cable.
  12  *     or one can use a standard stereo mini-jack to two RCA plugs cable.
  13  *     Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
  14  *    ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
  15  *    Notes on how to capture sound:
  16  *      The AC97 is used in the PLAYBACK direction.
  17  *      The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
  18  *      So, to record from the MIC, set the MIC Playback volume to max,
  19  *      unmute the MIC and turn up the MASTER Playback volume.
  20  *      So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
  21  *
  22  *    The only playback controls that currently do anything are: -
  23  *    Analog Front
  24  *    Analog Rear
  25  *    Analog Center/LFE
  26  *    SPDIF Front
  27  *    SPDIF Rear
  28  *    SPDIF Center/LFE
  29  *
  30  *    For capture from Mic in or Line in.
  31  *    Digital/Analog ( switch must be in Analog mode for CAPTURE. )
  32  *
  33  *    CAPTURE feedback into PLAYBACK
  34  *
  35  *  Changelog:
  36  *    Support interrupts per period.
  37  *    Removed noise from Center/LFE channel when in Analog mode.
  38  *    Rename and remove mixer controls.
  39  *  0.0.6
  40  *    Use separate card based DMA buffer for periods table list.
  41  *  0.0.7
  42  *    Change remove and rename ctrls into lists.
  43  *  0.0.8
  44  *    Try to fix capture sources.
  45  *  0.0.9
  46  *    Fix AC3 output.
  47  *    Enable S32_LE format support.
  48  *  0.0.10
  49  *    Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
  50  *  0.0.11
  51  *    Add Model name recognition.
  52  *  0.0.12
  53  *    Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
  54  *    Remove redundent "voice" handling.
  55  *  0.0.13
  56  *    Single trigger call for multi channels.
  57  *  0.0.14
  58  *    Set limits based on what the sound card hardware can do.
  59  *    playback periods_min=2, periods_max=8
  60  *    capture hw constraints require period_size = n * 64 bytes.
  61  *    playback hw constraints require period_size = n * 64 bytes.
  62  *  0.0.15

  71  *    Finally fix support for SB Live 24 bit. SB0410 and SB0413.
  72  *    The output codec needs resetting, otherwise all output is muted.
  73  *  0.0.20
  74  *    Merge "pci_disable_device(pci);" fixes.
  75  *  0.0.21
  76  *    Add 4 capture channels. (SPDIF only comes in on channel 0. )
  77  *    Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
  78  *
  79  *  BUGS:
