  3d stereo sound  http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=7335&highlight=openal
Comment:

1. The main reason why it doesn't work is to use stereo waves !!!
Stereo waves will cause OpenAl to play the sound as background music (like Audiere) !!!
If you use a mono wave it works: the nearer the player to the sounds position, the louder the sound is played. If the player left or right of the sound, the sound will played on left/right speaker...

2. 一般使用OpenAL..音效部分就是用wav格式, 背景音樂部份就是用ogg..
