Should you choose to float the floor on a vapour barrier, be sure to level the concrete slab first. There are often uneven patches, and that can cause the hollow sound as you walk over the floor. I used to use a fine sand and screed it over the slab. Takes a bit of care to level and keep level as you instal, but no voids under the flooring makes a much more stable job.
