* Framework borrowed from Massimo Piccioni's card-als100.c.
|

*
|
|
* NOTES
|
|
*
|
|
* Since Avance does not provide any meaningful documentation, and I
|
|
* bought an ALS4000 based soundcard, I was forced to base this driver
|
|
* on reverse engineering.
|
|
*
|
|
* Note: this is no longer true. Pretty verbose chip docu (ALS4000a.PDF)
|
|
* can be found on the ALSA web site.
|
|
*
|
|
* The ALS4000 seems to be the PCI-cousin of the ALS100. It contains an
|
|
* ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport
|
|
* interface. These subsystems can be mapped into ISA io-port space,
|
|
* using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ
|
|
* services to the subsystems.
|
|
*
|
|
* While ALS4000 is very similar to a SoundBlaster, the differences in
|
|
* DMA and capturing require more changes to the SoundBlaster than
|
|
* desirable, so I made this separate driver.
|
|
*
|
|
* The ALS4000 can do real full duplex playback/capture.
|
|
*
|
|
* FMDAC:
|
|
* - 0x4f -> port 0x14
|
|
* - port 0x15 |= 1
|
|
*
|
|
* Enable/disable 3D sound:
|
|
* - 0x50 -> port 0x14
|
|
* - change bit 6 (0x40) of port 0x15
|
|
*
|
|
* Set QSound:
|
|
* - 0xdb -> port 0x14
|
|
* - set port 0x15:
|
|
* 0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0)
|
|
*
|
|
* Set KSound:
|
|
* - value -> some port 0x0c0d
