Spatial sound using Media Texture


I have two different media textures, a mp4 with music. The thing is, I create the media texture, added the sound media, selected the spatial configuration, and on the Editor works fine, if I move, I can hear the 3d sound. But once I deployed to the ipad, both sound are like a 2D UI sound.

The thing is, on Editor, if I dont add any Media Sound, when I press play, I cannot hear any sound. But if I deploy on the ipad, I can hear the sound as a 2D. So looks like on ipad the media textures plays always the sound as a 2d. Anyone knows how to make the sound from a media texture be 3d?
