[Openal] Play mono as "stereo"

[Andrew Kerkel]

Actually I tried the source relative trick already - but I missed to set the source reference distance to 1 - that was the clue. You helped me a lot. :)
Thanks to all of you.

  Hi Andrew,

  If you want to play a mono sound as 2D then you should enable Head Relative mode using :-

  alSourcei(SourceID, AL_SOURCE_RELATIVE, AL_TRUE);

  The position you specify for the Source will now be relative to the Listener rather than a world co-ordinate. If you want the sound to play from all speakers set the Source position to 0,0,0. If you want the sound to play from in-front of the listener (like a 2D mono would) you can set the Source position to 0,0,-1. I would also set the Source Reference Distance parameter to 1.
