of reading a value cached in the driver.
*****************************************************************************************
* W2k/NT MIXER WARNING *
* Callbacks in W2k and NT do not currently work between applications. *
* If an application relies on an MM_MIXM_CONTROL_CHANGE message to update the display *
* in a second instance of the same application, this will not work. The application *
* that calls mixerSetControDetails() will receive a MM_MIXM_CONTROL_CHANGE, but that is *
* the only application that will receive the callback. *
* *
* This will be fixed in a future driver version. *
*****************************************************************************************

JUN-05-98 V132 Fixed bug where driver failed to return last buffers in certain
cases. Applies only to default "Hardware Buffering=off" case.
Corrected INI storeage of volume settings for ASI4030.
JUN-02-98 V131 Major change to how playback buffers are handled. By default, playback
buffers are now only returned to the application AFTER they
have been played. A new setting has been added to ASIWAV.INI to
support this. "Hardware Buffering=off", the default, will return
playback buffers to an application only after they have been played.
This means that the total audio buffering utilized equals the total
user buffers declared in the application. "Hardware Buffering=on"
allows the driver to return a buffer to the application before
it has been played. This allows the hardware buffer on the adapter
to completely fill up. In this case the total audio buffering utilized
equals the card buffer size (512k typical) plus user buffers. Note: With
hardware buffering on, the last playback buffer is always "held" in the
driver until playback has completed. The user may edit ASIWAV.INI to
enable hardware buffering.
Minor correction to INI storing of control settings when missing
adapter 1.
MAY-29-98 V130B AESEBU change for ASI4030.

controls fixed. Use of mixer handles inside the driver improved.
