/* GENERAL NOTES:

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.

/*
|
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.

/*
|
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.

/*
|
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.
