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. |
