INT 2F RC - InterWave Game API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running.  Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. - MIXER SETTINGS CHANGED BROADCAST
	AX = CD80h
Return: nothing
Desc:	called by an application controlling the InterWave chip's mixer
	  whenever the mixer's settings are changed
Range:	AH=CDh-ECh, selected by scanning for an available multiplex number
Note:	when an application intercepts this function call, it must read the
	  new mixer settings from the InterWave chip
