July 23rd, 2003 Version 1.3.8
------------------------------------
FUNCTIONAL CHANGES
-------------------
Fix bug that showed as an occassional loss of sound when starting Music on
the Pinball game. The problem was due to the original starving state additions,
which did not allow for data resuming from a starved condition, which is
what can happen in the test sequence. The fix was to change the code for the
change to KSSTATE_RUN to allow for pause or starving state in doing the resume.

------------------------------------
July 17th, 2003 Version 1.3.7
------------------------------------
FUNCTIONAL CHANGES
-------------------
It was discovered that V1.1.7 of Duraudio was built upon an outdated
version of duraudio. V1.3.7 is the same driver code, compiled with V1.1.9
of Duraudio, which is the 1.1.8 changes made to the latest base.

===========================================================================================
------------------------------------
July 11th, 2003 Version 1.3.6
------------------------------------
FUNCTIONAL CHANGES
-------------------
PRD table no longer contains an eot after last valid entry. Testing showed that
in high use scenarios, there was a race condition that could cause the enable
bit to not show the engine disabled for an amount of time, allowing the driver and
hardware to get out of sync. Instead, the driver will now pause the engine in low data
situations and restart it once additional data is available.
FILE CHANGES
-------------
GEODEWave.cpp
- Changed PRD table logic to use pause
Native.rc
- Changed version numbers
GX2Prop.rc
- Changed version numbers
DEFECTS CORRECTED
------------------
- Issue #157.7 - Loss of output when playing multiple sound files.
CAUSE: Previous fix for Static, created a race condition. The dma engine was
not clearing its enable bit when it stopped for a long enough period of
time that the driver and hardware could get out of sync. This only showed up
during high use (such as playing mulktiple files).
FIX: Remove previous EOT fix, and let the driver pause the hardware when it detects
a low data situation.
KNOWN ERRATA
--------------
None
===========================================================================================
------------------------------------
June 19th, 2003 Version 1.3.5
------------------------------------
FUNCTIONAL CHANGES
-------------------
PRD table now contains an eot after last valid entry, allowing for
data starvation with proper DMA shutdown. Appropriate startup code
also included
FILE CHANGES
-------------
- Updated to use DURAUDIO_1.1.8 files (Check DURAUDIO_1.1.8 release notes)
Duraudio.h
Duraudio.c
- Added functions and definitions used by DURAUDIO_1.1.7
- Added new code for OS_Sleep
GEODEWave.cpp
- Changed PRD table logic to use EOT
Native.rc
- Changed version numbers
GX2Prop.rc
- Changed version numbers
DEFECTS CORRECTED
------------------
- Issue #171.12 - static on playing.
CAUSE: Previous fix for BUZZ on pause, created a race condition. The dma engine
was being started and stopped as the number of buffers reached a low level, producing
static.
FIX: Build PRD table with EOT so that hardware will stop when it runs out of data
instead of trying to guess when data is ending due to low buffers.

None
===========================================================================================
------------------------------------
May 19th, 2003 Version 1.3.4

makefile
- Removed references to other manufacturer.
common.cpp
- Added Power management code.
GEODEWave.cpp
- Added the fix for issue 109.38 (Described below).
DEFECTS CORRECTED
------------------
- Issue #109.38 - Sound repeats making a buzzing noise.
CAUSE: On pause, MediaPlayer9 stops sending data and starves the driver.
The driver was not stopping the DMA only when head (Bottom of the
SGD list)
was equal tail (Top of the SGD list) and it was missing some
conditions.
The result was a repeat of the last SGD entry. That generated the
Buzzing noise.
FIX: Stopping the DMA anytime we have 2 or less SGD entries left to play.

KNOWN ERRATA
--------------
- Clicking on beginning of Playback and occasional loop on pause state.
- Caused by hard drive access.
The same behavior is seen on a SoundBlaster ES1371 card on our platform.
Erratas from the last versions with corrections/updates
-------------------------------------------------------
1. MP3 playback under XP takes up around 40% of CPU load..
- CORRECTION: The CPU load is high on .mp3 (40%) and .wav files (33%).
Same results were observed using a SoundBlaster ES1371 on
SP4GX22.
CPU loads on a Pentium III 800 Mhz system with a SoundBlaster
Live card using MediaPlayer are: .mp3: 16%, .wav: 13%.
The majority of the CPU load is used by WindowsMedia Player.
Playback of a .wav file in our hardware using SoundRecorder
takes up only 1 to 2%.
2. Line-in and microphone volume controls do not function correctly.
- CORRECTION: Line-In and Mic inputs function correctly.
3. Recording distortion at 0db in XP.
- CORRECTION: Recording works and it was verified in both Mic and Line-In
4. WDM audio driver does not install when XpressGraphics(TM) is present.
- UPDATE: Driver installs with Graphics driver Version 1.1.3 Beta.
5. Full duplex operation is not supported in this release.
- CORRECTION: Full-Duplex works since version 1.0.0
Tested this version with simultaneous recording (With
SoundRecorder) and playback (With MediaPlayer).
6. Headphone operation is not supported in this release..
- CORRECTION: There is no headphone support (Headphone output jack) on SP4GX22.
7. Combinations of ports (i.e., headphone, microphone, line-in, line-out) is not supported in
this release.
- CORRECTION: Such support does not exist.
8. Sound recording is not supported in this release.
- CORRECTION: Recording was tested and it works on both SoundRecorder and Cool edit
PRO.
9. Operation with the BTB_SWAPSIF flag enabled in BIOS (1.09) causes system crash.
- UPDATE: True for XpressROM 1.0.9, but the driver is currently working on XpressROM
1.12
