25 * - There are pops (we can't delay in trigger function, cause midlevel
26 * often need to trigger down and then up very quickly).
28 * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
33 * - The chip has one half duplex pcm (with very limited full duplex support).
35 * - Duplex stereophonic sound is impossible.
36 * - Record and playback must share the same frequency rate.
38 * - The driver use dma2 for playback and dma1 for capture.
44 * - there are a first full duplex pcm and a second playback only pcm
45 * (incompatible with first pcm capture)
47 * - there is support for the capture volume and ESS Spatializer 3D effect.
49 * - contrarily to some pages in DS_1869.PDF the rates can be set
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.
58 * - There is a major trouble I noted:
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.
63 * The same happens using Audio1 for captureing.
65 * The Windows driver does not suffer of this (although it use Audio1
66 * only for captureing). I'm unable to discover why.
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.
