ALSA: azt3328: add custom AC97 semi-emulation use standard ALSA AC97 layer
Make use of the very flexible ALSA ac97 layer (hooks for custom I/O!) on this weird AC97 copycat hardware, via semi-extended I/O translation/emulation. Some 5kB binary/loaded size saved (well... additional huge AC97 module penalty not factored in, of course ;-P). Given that the driver previously had 20kB that's not bad, but the much more important thing is to have AC97 layer stress-tested with a thoroughly weird AC97 copycat (or, simply put, if it were not for this AC97 test aspect, this effort would merely have been a nut job ;).

Say Y here to include support for Aztech AZF3328 (PCI168)
|
||||
soundcards.
|
||||
|
||||
Supported features: AC97-"conformant" mixer, MPU401/OPL3, analog I/O
|
||||
(16bit/8bit, many sample rates [<= 66.2kHz], NO hardware mixing),
|
||||
Digital Enhanced Game Port, 1.024MHz multimedia sequencer timer,
|
||||
ext. codec (I2S port), onboard amp (4W/4Ohms/ch), suspend/resume.
|
||||
|
||||
To compile this driver as a module, choose M here: the module
|
||||
will be called snd-azt3328.
