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  * - Zoom Video is implemented by sharing the FM DAC, thus the user can
53  *   have either FM playback or Video playback but not both simultaneously.
54  *   The Video Playback Switch mixer control toggles this choice.
55  *
56  * BUGS:
57  *
58  * - There is a major trouble I noted:
59  *
60  *   using both channel for playback stereo 16 bit samples at 44100 Hz
61  *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
62  *   
63  *   The same happens using Audio1 for captureing.
64  *
65  *   The Windows driver does not suffer of this (although it use Audio1
66  *   only for captureing). I'm unable to discover why.
67  *
68  */
69
70 /*
71  * ES1879 NOTES:
72  * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
73  *   seems to be effected (speaker_test plays a lower frequency). Can't find
74  *   anything in the datasheet to account for this, so a Video Playback Switch
75  *   control has been included to allow ZV to be enabled only when necessary.
76  *   Then again on at least one test system the 0x71 bit 6 enable bit is not 
77  *   needed for ZV, so maybe the datasheet is entirely wrong here.
