(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 * Separate ca0106.c into separate functional .c files. * 0.0.16 * Modified Copyright message. * 0.0.17 * Add iec958 file in proc file system to show status of SPDIF in. * 0.0.18 * Implement support for Line-in capture on SB Live 24bit. * * 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.
