Android (Including Oculus Go)

On Android you must request permission to use the microphone, see the Unity documentation for this here. If you use Android 6.0 or greater and API level 23 or greater there is a runtime permissions system which Unity makes available through the Android.Permissions, see the section titled "Runtime permissions in Android 6.0 (Marshmallow)" on this page.

ARM64

Dissonance includes ARM64 binaries compatible with Android, these are only enabled in Unity 2018.1+ (Unity 2017.4 does not support ARM64).
