      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.
