  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.
