/* * Copyright (c) by James Courtier-Dutton * Driver AUDIGYLS chips * Version: 0.0.11 * * 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. * (The AudigyLS uses the AC97 playback channel for capture. The AC97 capture channel is not used at all.) * Master * Mic (The one marked as playback) * Mic boost * Line (The one marked as playback) * 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 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".) * 0.0.11 * Add Model name recognition. * * BUGS: * Some stability problems when unloading the snd-audigyls kernel module. * -- * * TODO: * 4 Capture channels, only one implemented so far. * Other 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) * * 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.
