0009  * NOTES
0010  *
0011  *  The extended registers contain mixer settings which are largely
0012  *  untapped for the time being.
0013  *
0014  *  MPU401 and SPDIF are not supported yet.  I don't have the hardware
0015  *  to aid in coding and testing, so I won't bother.
0016  *
0017  *  To quickly load the module,
0018  *
0019  *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
0020  *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0 fmport=0x388
0021  *
0022  *  This card has two mixers and two PCM devices.  I've cheesed it such
0023  *  that recording and playback can be done through the same device.
0024  *  The driver "magically" routes the capturing to the AD1848 codec,
0025  *  and playback to the SB16 codec.  This allows for full-duplex mode
0026  *  to some extent.
0027  *  The utilities in alsa-utils are aware of both devices, so passing
0028  *  the appropriate parameters to amixer and alsactl will give you
0029  *  full control over both mixers.
