|
|---|
| 23 | *
|
|---|
| 24 | * BUGS:
|
|---|
| 25 | * - There are pops (we can't delay in trigger function, cause midlevel
|
|---|
| 26 | * often need to trigger down and then up very quickly).
|
|---|
| 27 | * Any ideas?
|
|---|
| 28 | * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
|
|---|
| 29 | */

|
|---|
| 31 | /*
|
|---|
| 32 | * ES1868 NOTES:
|
|---|
| 33 | * - The chip has one half duplex pcm (with very limited full duplex support).
|
|---|
| 34 | *
|
|---|
| 35 | * - Duplex stereophonic sound is impossible.
|
|---|
| 36 | * - Record and playback must share the same frequency rate.
|
|---|
| 37 | *
|
|---|
| 38 | * - The driver use dma2 for playback and dma1 for capture.
|

|---|
| 41 | /*
|
|---|
| 42 | * ES1869 NOTES:
|
|---|
| 43 | *
|
|---|
| 44 | * - there are a first full duplex pcm and a second playback only pcm
|
|---|
| 45 | * (incompatible with first pcm capture)
|
|---|
| 46 | *
|
|---|
| 47 | * - there is support for the capture volume and ESS Spatializer 3D effect.
|
|---|
| 48 | *
|
|---|
| 49 | * - contrarily to some pages in DS_1869.PDF the rates can be set
|
|---|
| 50 | * independently.
|
|---|
| 51 | *
|
|---|
| 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.
|
|---|
| 55 | *
|
|---|
| 56 | * BUGS:
|
|---|
| 57 | *
|
|---|
| 58 | * - There is a major trouble I noted:
|
|---|
| 59 | *
|
|---|
| 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.
|
|---|
| 62 | *
|
|---|
| 63 | * The same happens using Audio1 for captureing.
|
|---|
| 64 | *
|
|---|
| 65 | * The Windows driver does not suffer of this (although it use Audio1
|
|---|
| 66 | * only for captureing). I'm unable to discover why.
|
|---|
| 67 | *
|

|
|---|
| 70 | /*
|
|---|
| 71 | * ES1879 NOTES:
|
|---|
| 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.
