(Rates other that these do not work, even with "plug:front".) 50 * 0.0.11 51 * Add Model name recognition. 52 * 0.0.12 53 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. 54 * Remove redundent "voice" handling. 55 * 0.0.13 56 * Single trigger call for multi channels. 57 * 0.0.14 58 * Set limits based on what the sound card hardware can do. 59 * playback periods_min=2, periods_max=8 60 * capture hw constraints require period_size = n * 64 bytes. 61 * playback hw constraints require period_size = n * 64 bytes. 62 * 0.0.15 63 * Minor updates. 64 * 0.0.16 65 * Implement 192000 sample rate. 66 * 0.0.17 67 * Add support for SB0410 and SB0413. 68 * 0.0.18 69 * Modified Copyright message. 70 * 0.0.19 71 * Finally fix support for SB Live 24 bit. SB0410 and SB0413. 72 * The output codec needs resetting, otherwise all output is muted. 73 * 0.0.20 74 * Merge "pci_disable_device(pci);" fixes. 75 * 0.0.21 76 * Add 4 capture channels. (SPDIF only comes in on channel 0. ) 77 * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.) 78 * 0.0.22 79 * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901 80 * 0.0.23 81 * Implement support for Line-in capture on SB Live 24bit. 82 * 83 * BUGS: 84 * Some stability problems when unloading the snd-ca0106 kernel module. 85 * -- 86 * 87 * TODO: 88 * 4 Capture channels, only one implemented so far. 89 * Other capture rates apart from 48khz not implemented. 90 * MIDI 91 * -- 92 * GENERAL INFO: 93 * Model: SB0310 94 * P17 Chip: CA0106-DAT 95 * AC97 Codec: STAC 9721 96 * ADC: Philips 1361T (Stereo 24bit) 97 * DAC: WM8746EDS (6-channel, 24bit, 192Khz) 98 * 99 * GENERAL INFO: 100 * Model: SB0410 101 * P17 Chip: CA0106-DAT 102 * AC97 Codec: None 103 * ADC: WM8775EDS (4 Channel) 104 * DAC: CS4382 (114 dB, 24-Bit, 192 kHz, 8-Channel D/A Converter with DSD Support) 105 * SPDIF Out control switches between Mic in and SPDIF out. 106 * No sound out or mic input working yet. 107 * 108 * GENERAL INFO: 109 * Model: SB0413 110 * P17 Chip: CA0106-DAT 111 * AC97 Codec: None. 112 * ADC: Unknown 113 * DAC: Unknown 114 * Trying to handle it like the SB0410. 115 * 116 * This code was initally based on code from ALSA's emu10k1x.c which is: 117 * Copyright (c) by Francisco Moraes <fmoraes@nc.rr.com> 118 * 119 * This program is free software; you can redistribute it and/or modify 120 * it under the terms of the GNU General Public License as published by 121 * the Free Software Foundation; either version 2 of the License, or 122 * (at your option) any later version. 123 * 124 * This program is distributed in the hope that it will be useful, 125 * but WITHOUT ANY WARRANTY; without even the implied warranty of 126 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
