I've heard about using lighter agregate mixes, but not much in the way of details.

Is there a satisfactory (and lighter) replacement for stone/gravel for non-load-bearing concrete (say, for use in above-ground sound walls) ???

Check out the sack cement or cement supplier under and there is a logo that says TXI click on that. They make a light weight product and may have some litterature on the process. We use it in Our Readymix operation.
Good luck

There are also products that entrain massive amounts of air that will lighten the unit weight of the concrete in non-structural environments. This will also help with sound dampening. I don't know what size project(s) you are talking about, but your local ready mix concrete supplier should be able to help you with this. If not, I would talk to the people at WR Grace since this is one of their specialties: Grace Construction Products
