/*
|
|
* NOTES
|
|
*
|
|
* The extended registers contain mixer settings which are largely
|
|
* untapped for the time being.
|
|
*
|
|
* MPU401 and SPDIF are not supported yet. I don't have the hardware
|
|
* to aid in coding and testing, so I won't bother.
|
|
*
|
|
* To quickly load the module,
|
|
*
|
|
* modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
|
|
* sbdma16=5 wssport=0x530 wssirq=11 wssdma=0 fmport=0x388
|
|
*
|
|
* This card has two mixers and two PCM devices. I've cheesed it such
|
|
* that recording and playback can be done through the same device.
|
|
* The driver "magically" routes the capturing to the AD1848 codec,
|
|
* and playback to the SB16 codec. This allows for full-duplex mode
|
|
* to some extent.
|
|
* The utilities in alsa-utils are aware of both devices, so passing
|
|
* the appropriate parameters to amixer and alsactl will give you
|
|
* full control over both mixers.
