 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 fmport=0x388
 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.
