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
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.
