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. |
