/* GENERAL NOTES:
*
* BUGS:
* - There are pops (we can't delay in trigger function, cause midlevel
* often need to trigger down and then up very quickly).
* Any ideas?
* - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
*/
/*
* ES1868 NOTES:
* - The chip has one half duplex pcm (with very limited full duplex support).
*
* - Duplex stereophonic sound is impossible.
* - Record and playback must share the same frequency rate.
*
* - The driver use dma2 for playback and dma1 for capture.
*/
/*
* ES1869 NOTES:
*
* - there are a first full duplex pcm and a second playback only pcm
* (incompatible with first pcm capture)
*
* - there is support for the capture volume and ESS Spatializer 3D effect.
*
* - contrarily to some pages in DS_1869.PDF the rates can be set
* independently.
*
* BUGS:
*
* - There is a major trouble I noted:
*
* using both channel for playback stereo 16 bit samples at 44100 Hz
* the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
*
* The same happens using Audio1 for captureing.
*
* The Windows driver does not suffer of this (although it use Audio1
* only for captureing). I'm unable to discover why.
