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   It was discovered that V1.1.7 of Duraudio was built upon an outdated 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
   hw 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 HW 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 HW when it detects
                a low data situation.


KNOWN ERRATA 
--------------
None

===========================================================================================

------------------------------------
June 19th, 2003     Version 1.3.5

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 HW will stop when it runs out of data
instead of
                                trying to guess when data is ending due to low buffers.

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.

        - 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
Hawk.
                                        CPU loads on a Pentium III 800Mhz 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 is present.

                - UPDATE:       Driver installs with Graphics driver Version 1.1.3 Beta.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
