[ALSA] azt3328.c: add 3D sound mixer switch/rename controls
- add 3D sound pre-3D/post-3D switch, as seen in standard AC-97 - rename controls to shorter and more accurate strings Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

*
|
||||
* - builtin AC97 conformant codec (SNR over 80dB)
|

* (really AC97 compliant?? I really doubt it when looking
|
||||
* at the mixer register layout)
|
||||
* Note that "conformant" != "compliant"!! this chip's mixer register layout
|
||||
* *differs* from the standard AC97 layout:
|
||||
* they chose to not implement the headphone register (which is not a
|
||||
* problem since it's merely optional), yet when doing this, they committed
|
||||
* the grave sin of letting other registers follow immediately instead of
|
||||
* keeping a headphone dummy register, thereby shifting the mixer register
|
||||
* addresses illegally. So far unfortunately it looks like the very flexible
|
||||
* ALSA AC97 support is still not enough to easily compensate for such a
|
||||
* grave layout violation despite all tweaks and quirks mechanisms it offers.
|
||||
* - builtin genuine OPL3
|
||||
* - full duplex 16bit playback/record at independent sampling rate
|
||||
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??

* - figure out some cleverly evil scheme to possibly make ALSA AC97 code
