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 CMI8330 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.
