Modules: ES18xx driver Second of 4 es18xx.c patches culminating in Zoom Video support. This patch changes the 'record source' mux routines to reflect the fact that not all of the supported chipsets have 8 possible inputs. Some have 4 and some have 5. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879 and an ES1878 machine. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation. No additional testing was done on the ALSA cvs version. Signed-off-by: Mark Salazar <markTheCoder@justmyself.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>

/* 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.
