Track # 450

           adequately.

Track # 462

Package Release:	OS200055	

1.0.0  OS/2 Driver					(7/20/1999)

Track # 255
	*  Unable to load driver in Warp Connect.

	*  Pops during rapid wave file changes (i.e., open folder,
	   close it before the sound has finished). This was caused
	   by rapid wave out volume changes. Delaying codec write
	   for wave volume until a wave file starts playing fixes
	   this problem.

	*  Allocated shared interrupt.

Track # 228
	*  Warpmix saves the mixer settings and restores them when
	   run with "restoremix" cmd line parameter. The installation
	   scripts add this to the Startup folder to ensure that
           every time OS/2 boots, the mixer settings are restored.

	*  Added reboot notification to (un)install scripts.

	*  Set default recording source to mic, so Windows sound
	   recorder will work as expected.
