7 | * Framework borrowed from Massimo Piccioni's card-als100.c. | |
8 | * | |
9 | * NOTES | |
10 | * | |
11 | * Since Avance does not provide any meaningful documentation, and I | |
12 | * bought an ALS4000 based soundcard, I was forced to base this driver | |
13 | * on reverse engineering. | |
14 | * | |
15 | * Note: this is no longer true. Pretty verbose chip docu (ALS4000a.PDF) | |
16 | * can be found on the ALSA web site. | |
17 | * | |
18 | * The ALS4000 seems to be the PCI-cousin of the ALS100. It contains an | |
19 | * ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport | |
20 | * interface. These subsystems can be mapped into ISA io-port space, | |
21 | * using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ | |
22 | * services to the subsystems. | |
23 | * | |
24 | * While ALS4000 is very similar to a SoundBlaster, the differences in | |
25 | * DMA and capturing require more changes to the SoundBlaster than | |
26 | * desirable, so I made this separate driver. | |
27 | * | |
28 | * The ALS4000 can do real full duplex playback/capture. | |
29 | * | |
30 | * FMDAC: | |
31 | * - 0x4f -> port 0x14 | |
32 | * - port 0x15 |= 1 | |
33 | * | |
34 | * Enable/disable 3D sound: | |
35 | * - 0x50 -> port 0x14 | |
36 | * - change bit 6 (0x40) of port 0x15 | |
37 | * | |
38 | * Set QSound: | |
39 | * - 0xdb -> port 0x14 | |
40 | * - set port 0x15: | |
41 | * 0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0) | |
42 | * | |
43 | * Set KSound: | |
44 | * - value -> some port 0x0c0d | |
