VRgarden tutorials: Adding Sound
Introduction
Create an Audio Mixer for your project (you only need one)
Go to Assets >Create > Audio Mixer
Create an empty GameObject > Create Empty
Add a component to the GameObject: Audio Source
4. Import and choose your AudioClip, decide to Play on Awake (off if you trigger the sound through programming) and Loop the sound. For VR, move Spatial Blend to 1 and define the Max Distance (500 is for a background sound, are you using a smaller sound?)
5. In the Output of the Audio Source, choose Master (that’s your Audio Mixer).
