			*****************************************************************************************

			### Removed Adapter line from the mixer                      ###
			### Serial number and NvMem now appear in the first Line Out ###
			Microsoft Volume control will now work correctly.

			end of asiwav.ini (Win 3.1/95/98 only).

Sep-15-1999	V180	Win 3.1/95/98. Updated driver to transfer 32 k "chunks" of playback data

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.

			stability, b) CS8401 digital out now "unmuted", c) calibration 
			added for level/trim.

			record to avoid "cutting off" recorded audio.

			(fullscale).

MAR-17-98	V121	DSP code version 3.08b.
			ASIWAV.INI (in \windows) now records default volume settings.
			These are updated by a mixerClose() call. The volumes recorded in the
			INI file may be edited by hand. DSP code is more stable. Driver 
			should run for extended periods	without lockup. Bug with volume 
			controls fixed. Use of mixer handles inside the driver improved.
			Known problems:	1) MPEG visualization energy is not recorded correctly, 
			2) playback of certain joint stereo MPEG files exhibits distortion 
			on a 41xx.
