(Rates other that these do not work, even with "plug:front".) 51 * 0.0.11 52 * Add Model name recognition. 53 * 0.0.12 54 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. 55 * Remove redundent "voice" handling. 56 * 0.0.13 57 * Single trigger call for multi channels. 58 * 0.0.14 59 * Set limits based on what the sound card hardware can do. 60 * playback periods_min=2, periods_max=8 61 * capture hw constraints require period_size = n * 64 bytes. 62 * playback hw constraints require period_size = n * 64 bytes. 63 * 0.0.15 64 * Minor updates. 65 * 0.0.16 66 * Implement 192000 sample rate. 67 * 0.0.17 68 * Add support for SB0410 and SB0413. 69 * 0.0.18 70 * Modified Copyright message. 71 * 0.0.19 72 * Finally fix support for SB Live 24 bit.

(SPDIF only comes in on channel 0. ) 78 * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.) 79 * 0.0.22 80 * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901 81 * 0.0.23 82 * Implement support for Line-in capture on SB Live 24bit. 83 * 0.0.24 84 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC) 85 * 0.0.25 86 * Powerdown SPI DAC channels when not in use 87 * 88 * BUGS: 89 * Some stability problems when unloading the snd-ca0106 kernel module. 90 * -- 91 * 92 * TODO: 93 * 4 Capture channels, only one implemented so far. 94 * Other capture rates apart from 48khz not implemented. 95 * MIDI 96 * -- 97 * GENERAL INFO: 98 * Model: SB0310 99 * P17 Chip: CA0106-DAT 100 * AC97 Codec: STAC 9721 101 * ADC: Philips 1361T (Stereo 24bit) 102 * DAC: WM8746EDS (6-channel, 24bit, 192Khz) 103 * 104 * GENERAL INFO: 105 * Model: SB0410 106 * P17 Chip: CA0106-DAT 107 * AC97 Codec: None 108 * ADC: WM8775EDS (4 Channel) 109 * DAC: CS4382 (114 dB, 24-Bit, 192 kHz, 8-Channel D/A Converter with DSD Support) 110 * SPDIF Out control switches between Mic in and SPDIF out. 111 * No sound out or mic input working yet. 112 * 113 * GENERAL INFO: 114 * Model: SB0413 115 * P17 Chip: CA0106-DAT 116 * AC97 Codec: None. 117 * ADC: Unknown 118 * DAC: Unknown 119 * Trying to handle it like the SB0410. 120 * 121 * This code was initially based on code from ALSA's emu10k1x.c which is: 122 * Copyright (c) by Francisco Moraes <fmoraes@nc.rr.com> 123 */ 124 #include <linux/delay.h> 125 #include <linux/init.h> 126 #include <linux/interrupt.h> 127 #include <linux/pci.h> 128 #include <linux/slab.h> 129 #include <linux/module.h> 130 #include <linux/dma-mapping.h> 131 #include <sound/core.h> 132 #include <sound/initval.h> 133 #include <sound/pcm.h> 134 #include <sound/ac97_codec.h> 135 #include <sound/info.h> 136 137 MODULE_AUTHOR("James Courtier-Dutton <James@superbug.demon.co.uk>"); 138 MODULE_DESCRIPTION("CA0106"); 139 MODULE_LICENSE("GPL"); 140 MODULE_SUPPORTED_DEVICE("{{Creative,SB CA0106 chip}}"); 141 142 // module parameters (see "Module Parameters") 143 static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; 144 static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; 145 static bool enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; 146 static uint subsystem[SNDRV_CARDS]; /* Force card subsystem model */ 147 148 module_param_array(index, int, NULL, 0444); 149 MODULE_PARM_DESC(index, "Index value for the CA0106 soundcard."); 150 module_param_array(id, charp, NULL, 0444); 151 MODULE_PARM_DESC(id, "ID string for the CA0106 soundcard."); 152 module_param_array(enable, bool, NULL, 0444); 153 MODULE_PARM_DESC(enable, "Enable the CA0106 soundcard."); 154 module_param_array(subsystem, uint, NULL, 0444); 155 MODULE_PARM_DESC(subsystem, "Force card subsystem model."); 156 157 #include "ca0106.h" 158 159 static const struct snd_ca0106_details ca0106_chip_details[] = { 160 /* Sound Blaster X-Fi Extreme Audio.
