 * CHANGE LOG:
 * 03Jul03 - X. J. Scott (xjs):
 *   - Pm_GetDefaultInputDeviceID() and Pm_GetDefaultOutputDeviceID()
 *     now return id of first input and output devices in system,
 *     rather than returning 0 as before.
 *     This fix enables valid default port values to be returned.
 *     0 is returned if no such device is found.

 * This file only needs to implement pm_init(), which calls various

 * might need to register devices for winmm, directx, and others.
