Stereo moves between left and right speakers too quickly after 1.13

Since the snapshots for 1.13, compared to 1.12 and prior, the stereo sound has moved between the left and right speakers too quickly in comparison. It used to need to be very precise to get a sound to only play in one speaker but now it just needs to be offset slightly from the centre. This, along with many other inconsistencies, wouldn't have been made if the game didn't have to be rewritten.
