Example Issue: Missing scene references and duplicate components in the Fisticuffs demo

The Fisticuffs demo has several issues related to the scene setup, namely:

* Missing audio references in the Fisticuffs controller (_Controller object)
* Duplicate Audio source on _Controller object

Open the Fisticuffs demo scene and inspect the _Controller object in the Unity Editor. Check the audio references and Audio source components against the issue; done means the required audio references are present and the duplicate Audio source is removed.
