I've no hardware to tune it. 14 */ 15 16/* 17 * ES1868 NOTES: 18 * - The chip has one half duplex pcm (with very limited full duplex support). 19 * 20 * - Duplex stereophonic sound is impossible. 21 * - Record and playback must share the same frequency rate. 22 * 23 * - The driver use dma2 for playback and dma1 for capture. 24 */ 25 26/* 27 * ES1869 NOTES: 28 * 29 * - there are a first full duplex pcm and a second playback only pcm 30 * (incompatible with first pcm capture) 31 * 32 * - there is support for the capture volume and ESS Spatializer 3D effect. 33 * 34 * - contrarily to some pages in DS_1869.PDF the rates can be set 35 * independently. 36 * 37 * - Zoom Video is implemented by sharing the FM DAC, thus the user can 38 * have either FM playback or Video playback but not both simultaneously. 39 * The Video Playback Switch mixer control toggles this choice. 40 * 41 * BUGS: 42 * 43 * - There is a major trouble I noted: 44 * 45 * using both channel for playback stereo 16 bit samples at 44100 Hz 46 * the second pcm (Audio1) DMA slows down irregularly and sound is garbled. 47 * 48 * The same happens using Audio1 for captureing. 49 * 50 * The Windows driver does not suffer of this (although it use Audio1 51 * only for captureing). I'm unable to discover why. 52 * 53 */ 54 55/* 56 * ES1879 NOTES: 57 * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback 58 * seems to be effected (speaker_test plays a lower frequency). Can't find 59 * anything in the datasheet to account for this, so a Video Playback Switch 60 * control has been included to allow ZV to be enabled only when necessary. 61 * Then again on at least one test system the 0x71 bit 6 enable bit is not 62 * needed for ZV, so maybe the datasheet is entirely wrong here. 63 */ 64 65#include <linux/init.h> 66#include <linux/err.h> 67#include <linux/isa.h> 68#include <linux/pnp.h> 69#include <linux/isapnp.h> 70#include <linux/module.h> 71#include <linux/delay.h> 72#include <linux/io.h> 73 74#include <asm/dma.h> 75#include <sound/core.h> 76#include <sound/control.h> 77#include <sound/pcm.h> 78#include <sound/pcm_params.h> 79#include <sound/mpu401.h> 80#include <sound/opl3.h> 81#define SNDRV_LEGACY_FIND_FREE_IRQ 82#define SNDRV_LEGACY_FIND_FREE_DMA 83#include <sound/initval.h> 84 85struct snd_es18xx { 86 struct snd_card *card;
