   9  * NOTES
  10  *
  11  *  The extended registers contain mixer settings which are largely
  12  *  untapped for the time being.
  13  *
  14  *  MPU401 and SPDIF are not supported yet.  I don't have the hardware
  15  *  to aid in coding and testing, so I won't bother.
  16  *
  17  *  To quickly load the module,
  18  *
  19  *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
  20  *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0 fmport=0x388
  21  *
  22  *  This card has two mixers and two PCM devices.  I've cheesed it such
  23  *  that recording and playback can be done through the same device.
  24  *  The driver "magically" routes the capturing to the AD1848 codec,
  25  *  and playback to the SB16 codec.  This allows for full-duplex mode
  26  *  to some extent.
  27  *  The utilities in alsa-utils are aware of both devices, so passing
  28  *  the appropriate parameters to amixer and alsactl will give you
  29  *  full control over both mixers.
