  22/* 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.
  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.
