Questing Ram sounds are always at full volume, distance doesn't matter.

As far as I can tell, the sounds should be affected by distance, but the quest ram is loud (same volume as the ender dragon):

AIUI this means that for some distance, the volume would be capped and wouldn't start to decay until further out.

We could perhaps turn him down a bit?

I recall sounds being converted from stereo to mono fixing something related to sounds not fading properly, so I'll consider this resolved unless it's still too loud.
