| 23 | * |
| 24 | * BUGS: |
| 25 | * - There are pops (we can't delay in trigger function, cause midlevel |
| 26 | * often need to trigger down and then up very quickly). |
| 27 | * Any ideas? |
| 28 | * - Support for 16 bit DMA seems to be broken. 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). I'm unable to discover why. |
