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.

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  */

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.
