   3  *  Driver p16v chips
   4  *  Version: 0.25
   5  *
   6  *  FEATURES currently supported:
   7  *    Output fixed at S32_LE, 2 channel to hw:0,0
   8  *    Rates: 44.1, 48, 96, 192.
   9  *
  10  *  Changelog:
  11  *  0.8
  12  *    Use separate card based buffer for periods table.
  13  *  0.9
  14  *    Use 2 channel output streams instead of 8 channel.
  15  *       (8 channel output streams might be good for ASIO type output)
  16  *    Corrected speaker output, so Front -> Front etc.
  17  *  0.10
  18  *    Fixed missed interrupts.
  19  *  0.11
  20  *    Add Sound card model number and names.
  21  *    Add Analog volume controls.
  22  *  0.12
  23  *    Corrected playback interrupts. Now interrupt per period, instead of half period.
  24  *  0.13
  25  *    Use single trigger for multichannel.
  26  *  0.14
  27  *    Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
  28  *  0.15
  29  *    Force buffer_size / period_size == INTEGER.
  30  *  0.16
  31  *    Update p16v.c to work with changed alsa api.
  32  *  0.17
  33  *    Update p16v.c to work with changed alsa api. Removed boot_devs.
  34  *  0.18
  35  *    Merging with snd-emu10k1 driver.
  36  *  0.19
  37  *    One stereo channel at 24bit now works.
  38  *  0.20
  39  *    Added better register defines.
  40  *  0.21
  41  *    Integrated with snd-emu10k1 driver.
  42  *  0.22
  43  *    Removed #if 0 ... #endif
  44  *  0.23
  45  *    Implement different capture rates.
  46  *  0.24
  47  *    Implement different capture source channels.
  48  *    e.g. When HD Capture source is set to SPDIF,
  49  *    setting HD Capture channel to 0 captures from CDROM digital input.
  50  *    setting HD Capture channel to 1 captures from SPDIF in.
  51  *  0.25
  52  *    Include capture buffer sizes.
  53  *
  54  *  BUGS:
  55  *    Some stability problems when unloading the snd-p16v kernel module.
  56  *    --
  57  *
  58  *  TODO:
  59  *    SPDIF out.
  60  *    Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
  61  *    Currently capture fixed at 48000Hz.
