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.
