/* * Copyright (c) 2004 James Courtier-Dutton * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit * Version: 0.0.25 * * FEATURES currently supported: * Front, Rear and Center/LFE. * Surround40 and Surround51. * Capture from MIC an LINE IN input. * SPDIF digital playback of PCM stereo and AC3/DTS works. * (One can use a standard mono mini-jack to one RCA plugs cable. * or one can use a standard stereo mini-jack to two RCA plugs cable. * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.) * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. ) * Notes on how to capture sound: * The AC97 is used in the PLAYBACK direction. * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC. * So, to record from the MIC, set the MIC Playback volume to max, * unmute the MIC and turn up the MASTER Playback volume. * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume. * * The only playback controls that currently do anything are: - * Analog Front * Analog Rear * Analog Center/LFE * SPDIF Front * SPDIF Rear * SPDIF Center/LFE * * For capture from Mic in or Line in. * Digital/Analog ( switch must be in Analog mode for CAPTURE. ) * * CAPTURE feedback into PLAYBACK * * Changelog: * Support interrupts per period. * Removed noise from Center/LFE channel when in Analog mode. * Rename and remove mixer controls. * 0.0.6 * Use separate card based DMA buffer for periods table list. * 0.0.7 * Change remove and rename ctrls into lists. * 0.0.8 * Try to fix capture sources. * 0.0.9 * Fix AC3 output. * Enable S32_LE format support. * 0.0.10 * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".) * 0.0.11 * Add Model name recognition. * 0.0.12 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. * Remove redundent "voice" handling. * 0.0.13 * Single trigger call for multi channels. * 0.0.14 * Set limits based on what the sound card hardware can do. * playback periods_min=2, periods_max=8 * capture hw constraints require period_size = n * 64 bytes. * playback hw constraints require period_size = n * 64 bytes. * 0.0.15 * Minor updates. * 0.0.16 * Implement 192000 sample rate. * 0.0.17 * Add support for SB0410 and SB0413. * 0.0.18 * Modified Copyright message. * 0.0.19 * Finally fix support for SB Live 24 bit. SB0410 and SB0413. * The output codec needs resetting, otherwise all output is muted. * 0.0.20 * Merge "pci_disable_device(pci);" fixes. * 0.0.21 * Add 4 capture channels. (SPDIF only comes in on channel 0. ) * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.) * 0.0.22 * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901 * 0.0.23 * Implement support for Line-in capture on SB Live 24bit. * 0.0.24 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC) * 0.0.25 * Powerdown SPI DAC channels when not in use * * BUGS: * Some stability problems when unloading the snd-ca0106 kernel module. * -- * * TODO: * 4 Capture channels, only one implemented so far. * Other capture rates apart from 48khz not implemented. * MIDI * -- * GENERAL INFO: * Model: SB0310 * P17 Chip: CA0106-DAT * AC97 Codec: STAC 9721 * ADC: Philips 1361T (Stereo 24bit) * DAC: WM8746EDS (6-channel, 24bit, 192Khz) * * GENERAL INFO: * Model: SB0410 * P17 Chip: CA0106-DAT * AC97 Codec: None * ADC: WM8775EDS (4 Channel) * DAC: CS4382 (114 dB, 24-Bit, 192 kHz, 8-Channel D/A Converter with DSD Support) * SPDIF Out control switches between Mic in and SPDIF out. * No sound out or mic input working yet. * * GENERAL INFO: * Model: SB0413 * P17 Chip: CA0106-DAT * AC97 Codec: None. * ADC: Unknown * DAC: Unknown * Trying to handle it like the SB0410. * * This code was initally based on code from ALSA's emu10k1x.c which is: * Copyright (c) by Francisco Moraes * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
