  23  * NOTES
  24  *
  25  *  The extended registers contain mixer settings which are largely
  26  *  untapped for the time being.
  27  *
  28  *  MPU401 and SPDIF are not supported yet.  I don't have the hardware
  29  *  to aid in coding and testing, so I won't bother.
  30  *
  31  *  To quickly load the module,
  32  *
  33  *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
  34  *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0
  35  *
  36  *  This card has two mixers and two PCM devices.  I've cheesed it such
  37  *  that recording and playback can be done through the same device.
  38  *  The driver "magically" routes the capturing to the AD1848 codec,
  39  *  and playback to the SB16 codec.  This allows for full-duplex mode
  40  *  to some extent.
  41  *  The utilities in alsa-utils are aware of both devices, so passing
  42  *  the appropriate parameters to amixer and alsactl will give you
  43  *  full control over both mixers.
