### Setting Up the Program

Before using PMADDE, OS/2 2.x with MMPM/2 must be installed on your computer. The PMADDE source files are located in the DDK\MMOS2\MMTOOLKT\ NEATSTUF\PMADDE subdirectory. To build the PMADDE program, change to the PMADDE subdirectory, type NMAKE, and press Enter. Your output is the executable file (PMADDE.EXE). You can then type PMADDE from the command line to start the program. The Audio Device Driver Exerciser window is displayed. [Artwork not shown]

The PMADDE program defaults to the first waveform audio device it locates. To change the default option, select Options. Select Change Device to display the Change Audio Device window. [Artwork not shown]

This window contains information about each installed audio device including the logical device name, physical device name, and product information. Select the audio device you want to test.
