1 /* 2 * Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk> 3 * Driver p16v chips 4 * Version: 0.25 5 * 6 * FEATURES currently supported: 7 * Output fixed at S32_LE, 2 channel to hw:0,0 8 * Rates: 44.1, 48, 96, 192. 9 * 10 * Changelog: 11 * 0.8 12 * Use separate card based buffer for periods table. 13 * 0.9 14 * Use 2 channel output streams instead of 8 channel. 15 * (8 channel output streams might be good for ASIO type output) 16 * Corrected speaker output, so Front -> Front etc. 17 * 0.10 18 * Fixed missed interrupts. 19 * 0.11 20 * Add Sound card model number and names. 21 * Add Analog volume controls. 22 * 0.12 23 * Corrected playback interrupts. Now interrupt per period, instead of half period. 24 * 0.13 25 * Use single trigger for multichannel. 26 * 0.14 27 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. 28 * 0.15 29 * Force buffer_size / period_size == INTEGER. 30 * 0.16 31 * Update p16v.c to work with changed alsa api. 32 * 0.17 33 * Update p16v.c to work with changed alsa api. Removed boot_devs. 34 * 0.18 35 * Merging with snd-emu10k1 driver. 36 * 0.19 37 * One stereo channel at 24bit now works. 38 * 0.20 39 * Added better register defines. 40 * 0.21 41 * Integrated with snd-emu10k1 driver. 42 * 0.22 43 * Removed #if 0 ... #endif 44 * 0.23 45 * Implement different capture rates. 46 * 0.24 47 * Implement different capture source channels. 48 * e.g. When HD Capture source is set to SPDIF, 49 * setting HD Capture channel to 0 captures from CDROM digital input. 50 * setting HD Capture channel to 1 captures from SPDIF in. 51 * 0.25 52 * Include capture buffer sizes. 53 * 54 * BUGS: 55 * Some stability problems when unloading the snd-p16v kernel module. 56 * -- 57 * 58 * TODO: 59 * SPDIF out. 60 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. 61 * Currently capture fixed at 48000Hz. 62 * 63 * -- 64 * GENERAL INFO: 65 * Model: SB0240 66 * P16V Chip: CA0151-DBS 67 * Audigy 2 Chip: CA0102-IAT 68 * AC97 Codec: STAC 9721 69 * ADC: Philips 1361T (Stereo 24bit) 70 * DAC: CS4382-K (8-channel, 24bit, 192Khz) 71 * 72 * This code was initially based on code from ALSA's emu10k1x.c which is: 73 * Copyright (c) by Francisco Moraes <fmoraes@nc.rr.com> 74 * 75 * This program is free software; you can redistribute it and/or modify 76 * it under the terms of the GNU General Public License as published by 77 * the Free Software Foundation; either version 2 of the License, or 78 * (at your option) any later version. 79 * 80 * This program is distributed in the hope that it will be useful, 81 * but WITHOUT ANY WARRANTY; without even the implied warranty of 82 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
