The minimum for surround with height is 8 speakers, for Ambisonics 1st

probably need 12+ speakers, although I suspect there could be a
solution with less speakers than 12. (Feeback welcome...)
Some have tried to reproduce "some" height information via a 7.1
layout. (And even 5.1, but here there are severe limitations.)
Can anyone shed further light on the usefulness of the 3D 7.1 layout that
Richard Furse's player offers? Possibly only a segment of a sphere, rather
than full sphere, but is it useful *enough*?
there is an AES paper by simon goodwin that deals with this layout:

the rationale is that you can deliver a pre-decoded stream over the
eight channels of a hdmi link and obtain some sort of 3D, while
retaining meaningful values of spouse acceptance factor :)
here's another very interesting study about the gaming market, and why
or why not it might be a spearhead for spatial audio at home:
