   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.

  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  *
  53  */
  54
  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.
