Hello,
to have the sound coming out from left or right speakers, as example based on the camera rotation in the scene, why does the sound have to be mono? Because mono has a bad quality, stereo sounds much better.
In my scene, the sound only comes out from left or right speakers (based on camera rotation) if the ogg file is mono. But as mentioned, mono has a much worse quality. Why not supporting stereo? A stereo sound could be played from left or right speakers only too. I mean it's not like described in the manual, stereo sounds to not contain the data to know when to play from right or left speakers. The stereo sound just needs to be treated like the mono file.
