Sounds hearable from the top

Hello, I have a problem, I made a 3D sound in my game but I dont know how to make sounds under character sounds another than that over the character. I was making 3D sound based on Fmod API/ low level guide. I can proceed to the source of the sound in 2D but I cant make it in 3D. Is it even possible in Fmod? If yes, can u tell me names of the functions what I need to know/use?

You can use Channel::setMode to change between FMOD_2D and FMOD_3D.
