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
54 * - There is a major trouble I noted:
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.
59 * The same happens using Audio1 for captureing.
61 * The Windows driver does not suffer of this (although it use Audio1
62 * only for captureing). I'm unable to discover why.
