0007 /* GENERAL NOTES:
0008  *
0009  * BUGS:
0010  * - There are pops (we can't delay in trigger function, cause midlevel
0011  *   often need to trigger down and then up very quickly).
0012  *   Any ideas?
0013  * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
0014  */
0015
0016 /*
0017  * ES1868  NOTES:
0018  * - The chip has one half duplex pcm (with very limited full duplex support).
0019  *
0020  * - Duplex stereophonic sound is impossible.
0021  * - Record and playback must share the same frequency rate.
0022  *
0023  * - The driver use dma2 for playback and dma1 for capture.
0024  */
0025
0026 /*
0027  * ES1869 NOTES:
0028  *
0029  * - there are a first full duplex pcm and a second playback only pcm
0030  *   (incompatible with first pcm capture)
0031  *
0032  * - there is support for the capture volume and ESS Spatializer 3D effect.
0033  *
0034  * - contrarily to some pages in DS_1869.PDF the rates can be set
0035  *   independently.
0036  *
0037  * - Zoom Video is implemented by sharing the FM DAC, thus the user can
0038  *   have either FM playback or Video playback but not both simultaneously.
0039  *   The Video Playback Switch mixer control toggles this choice.
0040  *
0041  * BUGS:
0042  *
0043  * - There is a major trouble I noted:
0044  *
0045  *   using both channel for playback stereo 16 bit samples at 44100 Hz
0046  *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
0047  *
0048  *   The same happens using Audio1 for captureing.
0049  *
0050  *   The Windows driver does not suffer of this (although it use Audio1
0051  *   only for captureing). I'm unable to discover why.
0052  *
0053  */
0054
0055 /*
0056  * ES1879 NOTES:
0057  * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
0058  *   seems to be effected (speaker_test plays a lower frequency). Can't find
0059  *   anything in the datasheet to account for this, so a Video Playback Switch
0060  *   control has been included to allow ZV to be enabled only when necessary.
0061  *   Then again on at least one test system the 0x71 bit 6 enable bit is not
0062  *   needed for ZV, so maybe the datasheet is entirely wrong here.
