  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  * BUGS:
  53  *
  54  * - There is a major trouble I noted:
  55  *
  56  *   using both channel for playback stereo 16 bit samples at 44100 Hz
  57  *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
  58  *
  59  *   The same happens using Audio1 for captureing.
  60  *
  61  *   The Windows driver does not suffer of this (although it use Audio1
  62  *   only for captureing). I'm unable to discover why.
