Open unnamedsoldier.cfg from your MOH\main\configs folder with Wordpad, and find the line that says:
[code:2cbc3]seta s_milesdriver "Miles Fast 2D Positional Audio"[/code:2cbc3]
change the "Miles Fast 2D Positional Audio" part to one of the following:
[code:2cbc3]"Aureal A3D interactive (TM)"
"Aureal A3D 2.0 (TM)"
"Creative Labs EAX (TM)"
"Creative Labs EAX 2 (TM)"
"DirectSound3D 7 + Software - Full HRTF"
"DirectSound3D 7 + Software - Light HRTF"
"DirectSound3D 7 + Software - Pan and Volume"
"DirectSound3D Hardware Support"
"DirectSound3D Software Support"
"Dolby Surround"[/code:2cbc3]
Depending on your sound card, drivers, and hardware acceleration, results vary. Whew. . .
