| /* GENERAL NOTES: |
| * |
| * BUGS: |
| * - There are pops (we can't delay in trigger function, cause midlevel |
| * often need to trigger down and then up very quickly). |
| * Any ideas? |
| * - Support for 16 bit DMA seems to be broken. 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. |
| * |
| * 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. |
