Hmm, an orientation vector of (0,0,0) means omnidirectional sound and is valid for OpenAL. The strange part is that it does return (0,0,0) for me every time.. > Perhaps this explains why the most recent cvs update produces; Not really I updated the initialization of the sound sample position to prevent NaN's (by initializing it to SGGeod::fromDeg(0,0) but that places it far, far away from the sound manager that was still at (0,0) in OpenAL location. I've updated that code in SimGear and added a third test program that tests (two) different lat/lon positions.
