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. | |
