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.
