Hi everyone,
I’ve started this course using Unity 5.6 in Ubuntu and found out that 3D Sound was missing. Searched the docs and found that for you guys using Unity 5 the default sound is 2D and you can blend 2D and 3D in the Spatial Blend properties inside Audio Source when you bring it under a new component.
Full docs can be read here:
Unity 5 Audio Upgrade
Hope this helps.
Cheers…
