3D Audio ist not working

The AudioDuck asset produces a sound, but the amplitude of the sound does not depend on the listeners position.

The Audio Duck asset works as intended as it is using a global audio emitter on a scene to play the quack sound. However, positional audio emitters do not seem to work when loaded.

It seems that the AudioContext treats mono audio files as having two channels. This could be a cause of this issue
