I've no hardware to tune it. 29 */ 30 31 /* 32 * ES1868 NOTES: 33 * - The chip has one half duplex pcm (with very limited full duplex support). 34 * 35 * - Duplex stereophonic sound is impossible. 36 * - Record and playback must share the same frequency rate. 37 * 38 * - The driver use dma2 for playback and dma1 for capture. 39 */ 40 41 /* 42 * ES1869 NOTES: 43 * 44 * - there are a first full duplex pcm and a second playback only pcm 45 * (incompatible with first pcm capture) 46 * 47 * - there is support for the capture volume and ESS Spatializer 3D effect. 48 * 49 * - contrarily to some pages in DS_1869.PDF the rates can be set 50 * independently. 51 * 52 * BUGS: 53 * 54 * - There is a major trouble I noted: 55 * 56 * using both channel for playback stereo 16 bit samples at 44100 Hz 57 * the second pcm (Audio1) DMA slows down irregularly and sound is garbled. 58 * 59 * The same happens using Audio1 for captureing. 60 * 61 * The Windows driver does not suffer of this (although it use Audio1 62 * only for captureing).
