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 *
95b71296
MS		 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 *
1da177e4
LT		 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 *
53 */

MS		 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.
