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).
