Any game that uses the Wwise integration must load the content/audio/Init .wwise_dep resource, which is automatically generated by the Wwise integration, in the boot package.
For example:
wwise_dep = [ "wwise/Init" ]
In order to play a sound from a sound bank, you must load that sound bank into the game at runtime. The bank can be loaded through Flow, Lua, or by adding its .wwise_dep resource to a resource package like the Init resource shown above.
See also Load sound banks at runtime.
By default new game projects are configured to move the Wwise listener 0 to the match the camera position. Search for WwiseWorld.set_listener in the Lua scripts to see where this is done, or to modify the implementation. The Lua API portion of the documentation has more information on the listener interface.
