It appears that ‘rs3d_PlaySound()’ and ‘rs3d_PlayJukeBox(0,false,false)’ both work for me, but ‘rs3d_PlayIn3D(true)’ does not. I tried swapping in ‘rs3d_PlayIn3D(true)’ for ‘rs3d_PlayJukeBox(0,false,true)’ to trigger music files in the ‘realspace3d_v0.10.0_sample.unitypackage’ sample scene, and it seemed to work there, so I’m guessing there’s a bug with the (v0.10.7) 18Aug15 build. In any case, I can move forward now. Thanks for making such a fantastic binaural 3D audio solution.
