I've no hardware to tune it. */ /* * ES1868 NOTES: * - The chip has one half duplex pcm (with very limited full duplex support). * * - Duplex stereophonic sound is impossible. * - Record and playback must share the same frequency rate. * * - The driver use dma2 for playback and dma1 for capture. */ /* * ES1869 NOTES: * * - there are a first full duplex pcm and a second playback only pcm * (incompatible with first pcm capture) * * - there is support for the capture volume and ESS Spatializer 3D effect. * * - contrarily to some pages in DS_1869.PDF the rates can be set * independently. * * - Zoom Video is implemented by sharing the FM DAC, thus the user can * have either FM playback or Video playback but not both simultaneously. * The Video Playback Switch mixer control toggles this choice. * * BUGS: * * - There is a major trouble I noted: * * using both channel for playback stereo 16 bit samples at 44100 Hz * the second pcm (Audio1) DMA slows down irregularly and sound is garbled. * * The same happens using Audio1 for captureing. * * The Windows driver does not suffer of this (although it use Audio1 * only for captureing). I'm unable to discover why. * */ /* * ES1879 NOTES: * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback * seems to be effected (speaker_test plays a lower frequency). Can't find * anything in the datasheet to account for this, so a Video Playback Switch * control has been included to allow ZV to be enabled only when necessary. * Then again on at least one test system the 0x71 bit 6 enable bit is not * needed for ZV, so maybe the datasheet is entirely wrong here. */ #include <linux/init.h> #include <linux/err.h> #include <linux/isa.h> #include <linux/pnp.h> #include <linux/isapnp.h> #include <linux/module.h> #include <linux/delay.h> #include <linux/io.h> #include <asm/dma.h> #include <sound/core.h> #include <sound/control.h> #include <sound/pcm.h> #include <sound/pcm_params.h> #include <sound/mpu401.h> #include <sound/opl3.h> #define SNDRV_LEGACY_FIND_FREE_IRQ #define SNDRV_LEGACY_FIND_FREE_DMA #include <sound/initval.h> #define PFX "es18xx: " struct snd_es18xx { unsigned long port;
