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.
