  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. * ES1868 NOTES:
  32. * - The chip has one half duplex pcm (with very limited full duplex support).
  33. *
  34. * - Duplex stereophonic sound is impossible.
  35. * - Record and playback must share the same frequency rate.
  36. *
  37. * - The driver use dma2 for playback and dma1 for capture.
  38. */
  39. /*
  40. * ES1869 NOTES:
  41. *
  42. * - there are a first full duplex pcm and a second playback only pcm
  43. * (incompatible with first pcm capture)
  44. *
  45. * - there is support for the capture volume and ESS Spatializer 3D effect.
  46. *
  47. * - contrarily to some pages in DS_1869.PDF the rates can be set
  48. * independently.
  49. *
  50. * - Zoom Video is implemented by sharing the FM DAC, thus the user can
  51. * have either FM playback or Video playback but not both simultaneously.
  52. * The Video Playback Switch mixer control toggles this choice.
  53. *
  54. * BUGS:
  55. *
  56. * - There is a major trouble I noted:
  57. *
  58. * using both channel for playback stereo 16 bit samples at 44100 Hz
  59. * the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
  60. *
  61. * The same happens using Audio1 for captureing.
  62. *
  63. * The Windows driver does not suffer of this (although it use Audio1
  64. * only for captureing). I'm unable to discover why.
  65. *
  66. */
  67. /*
  68. * ES1879 NOTES:
  69. * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
  70. * seems to be effected (speaker_test plays a lower frequency). Can't find
  71. * anything in the datasheet to account for this, so a Video Playback Switch
  72. * control has been included to allow ZV to be enabled only when necessary.
  73. * Then again on at least one test system the 0x71 bit 6 enable bit is not
  74. * needed for ZV, so maybe the datasheet is entirely wrong here.
