7 /* GENERAL NOTES:
8  *
9  * BUGS:
10  * - There are pops (we can't delay in trigger function, cause midlevel
11  *   often need to trigger down and then up very quickly).
12  *   Any ideas?
13  * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
14  */
15 
16 /*
17  * ES1868  NOTES:
18  * - The chip has one half duplex pcm (with very limited full duplex support).
19  *
20  * - Duplex stereophonic sound is impossible.
21  * - Record and playback must share the same frequency rate.
22  *
23  * - The driver use dma2 for playback and dma1 for capture.
24  */
25 
26 /*
27  * ES1869 NOTES:
28  *
29  * - there are a first full duplex pcm and a second playback only pcm
30  *   (incompatible with first pcm capture)
31  *
32  * - there is support for the capture volume and ESS Spatializer 3D effect.
33  *
34  * - contrarily to some pages in DS_1869.PDF the rates can be set
35  *   independently.
36  *
37  * - Zoom Video is implemented by sharing the FM DAC, thus the user can
38  *   have either FM playback or Video playback but not both simultaneously.
39  *   The Video Playback Switch mixer control toggles this choice.
40  *
41  * BUGS:
42  *
43  * - There is a major trouble I noted:
44  *
45  *   using both channel for playback stereo 16 bit samples at 44100 Hz
46  *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
47  *
48  *   The same happens using Audio1 for captureing.
49  *
50  *   The Windows driver does not suffer of this (although it use Audio1
51  *   only for captureing). I'm unable to discover why.
52  *

55 /*
56  * ES1879 NOTES:
57  * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
58  *   seems to be effected (speaker_test plays a lower frequency). Can't find
59  *   anything in the datasheet to account for this, so a Video Playback Switch
60  *   control has been included to allow ZV to be enabled only when necessary.
61  *   Then again on at least one test system the 0x71 bit 6 enable bit is not
62  *   needed for ZV, so maybe the datasheet is entirely wrong here.
