Mono sounds are spatially adjusted, whereas stereo sounds are not. Even when 
centered, 3D sound will decrease the overall per-channel volume so it's about 
as loud as if it was playing out of one speaker. This is so the sound doesn't 
get quieter as it moves away from center even while well within the reference 
distance (where it's typically supposed to stay at max gain).

I unfortunately cannot think of an easy way to solve this, other than turning 
it into a stereo stream, or increasing the gain past 1.0 (although doing that 
isn't very reliable across implementations).
