Changeset 6269 for code/branches/presentation2/src/orxonox/sound/WorldSound.cc

Message:

At last, found the sound bug: A long time ago somebody wrote AL_POSITION instead of AL_ORIENTATION and the orientation of the listener was updated AFTER the position.
Also fixed a problem with the wrong quaternion axis for the listener orientation.
