[Openal] 3D Sound and moving Listener

Hi!
I'm having the same problem with the listener not moving.

Moving (mono) sources with a static listener do work but static (mono) sources with a moving listener do not work. Only the first position change for the listener object seems to be taken into account for the panning/volume and so on. Any other "alListener(AL_POSITION...)" call has no effect. I tried changing the AL_SOURCE_RELATIVE flag for the sources, but it has no effect either. I found a demo on the internet where one can move the listener, this demo is perfect to illustrate the problem. If I change the positions for the sources instead, the demo will work properly.

I am running Windows XP using the latest OpenAL dlls and the Generic Hardware device.

P.S: On a different topic, it would be nice if the AL specification would mention that stereo sources are computed differently than mono sources.
