PlaySoundXY
From Original War Support Wiki
Plays a .wav sound located in "sound\" at the specified hexagons. The name of the .wav files should't contain the extension ".wav" in the SAIL code.
If the position isn't valid sound won't play.

PlaySoundXYLoop(x, y, 'filename');
For play sound normally (global):
PlaySoundXY(-100, -1, 'filename');
Example usage:
PlaySoundXY(-100, -1, 'MyCrazyTrack');
Only works in the latest version (2.0.6.143 and higher).
