1 /* 2 * Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk> 3 * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit 4 * Version: 0.0.25 5 * 6 * FEATURES currently supported: 7 * Front, Rear and Center/LFE. 8 * Surround40 and Surround51. 9 * Capture from MIC an LINE IN input. 10 * SPDIF digital playback of PCM stereo and AC3/DTS works. 11 * (One can use a standard mono mini-jack to one RCA plugs cable. 12 * or one can use a standard stereo mini-jack to two RCA plugs cable. 13 * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.) 14 * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. ) 15 * Notes on how to capture sound: 16 * The AC97 is used in the PLAYBACK direction. 17 * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC. 18 * So, to record from the MIC, set the MIC Playback volume to max, 19 * unmute the MIC and turn up the MASTER Playback volume. 20 * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume. 21 * 22 * The only playback controls that currently do anything are: - 23 * Analog Front 24 * Analog Rear 25 * Analog Center/LFE 26 * SPDIF Front 27 * SPDIF Rear 28 * SPDIF Center/LFE 29 * 30 * For capture from Mic in or Line in. 31 * Digital/Analog ( switch must be in Analog mode for CAPTURE. ) 32 * 33 * CAPTURE feedback into PLAYBACK 34 * 35 * Changelog: 36 * Support interrupts per period. 37 * Removed noise from Center/LFE channel when in Analog mode. 38 * Rename and remove mixer controls. 39 * 0.0.6 40 * Use separate card based DMA buffer for periods table list. 41 * 0.0.7 42 * Change remove and rename ctrls into lists. 43 * 0.0.8 44 * Try to fix capture sources. 45 * 0.0.9 46 * Fix AC3 output. 47 * Enable S32_LE format support. 48 * 0.0.10 49 * Enable playback 48000 and 96000 rates. (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 * 0.0.24 83 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC) 84 * 0.0.25 85 * Powerdown SPI DAC channels when not in use 86 * 87 * BUGS: 88 * Some stability problems when unloading the snd-ca0106 kernel module. 89 * -- 90 * 91 * TODO: 92 * 4 Capture channels, only one implemented so far. 93 * Other capture rates apart from 48khz not implemented. 94 * MIDI 95 * -- 96 * GENERAL INFO: 97 * Model: SB0310 98 * P17 Chip: CA0106-DAT 99 * AC97 Codec: STAC 9721 100 * ADC: Philips 1361T (Stereo 24bit) 101 * DAC: WM8746EDS (6-channel, 24bit, 192Khz) 102 * 103 * GENERAL INFO: 104 * Model: SB0410 105 * P17 Chip: CA0106-DAT 106 * AC97 Codec: None 107 * ADC: WM8775EDS (4 Channel) 108 * DAC: CS4382 (114 dB, 24-Bit, 192 kHz, 8-Channel D/A Converter with DSD Support) 109 * SPDIF Out control switches between Mic in and SPDIF out. 110 * No sound out or mic input working yet. 111 * 112 * GENERAL INFO: 113 * Model: SB0413 114 * P17 Chip: CA0106-DAT 115 * AC97 Codec: None. 116 * ADC: Unknown 117 * DAC: Unknown 118 * Trying to handle it like the SB0410. 119 * 120 * This code was initially based on code from ALSA's emu10k1x.c which is: 121 * Copyright (c) by Francisco Moraes <fmoraes@nc.rr.com> 122 * 123 * This program is free software; you can redistribute it and/or modify 124 * it under the terms of the GNU General Public License as published by 125 * the Free Software Foundation; either version 2 of the License, or 126 * (at your option) any later version. 127 * 128 * This program is distributed in the hope that it will be useful, 129 * but WITHOUT ANY WARRANTY; without even the implied warranty of 130 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
