- /* 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.
- *
- * - Zoom Video is implemented by sharing the FM DAC, thus the user can
- * have either FM playback or Video playback but not both simultaneously.
- * The Video Playback Switch mixer control toggles this choice.
- *
- * 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.
- *
- */
- /*
- * ES1879 NOTES:
- * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
- * seems to be effected (speaker_test plays a lower frequency). Can't find
- * anything in the datasheet to account for this, so a Video Playback Switch
- * control has been included to allow ZV to be enabled only when necessary.
- * Then again on at least one test system the 0x71 bit 6 enable bit is not
- * needed for ZV, so maybe the datasheet is entirely wrong here.
